A Tribute to the Rolling Boulder

This is my 12th done-in-under-a-week game. It’s also my Assembly gamedev competition entry. Which means it was published on the Assembly website a bit earlier than it is published here. And thus it “leaked” to the internet and was blogged already by the2bears, indygamer and soldat movies.

The game is open to harsh critique and wish me good luck at the Assembly gamedev combo.

You play as the infamous rolling boulder. Roll over the archeologists and protect the honor of the golden idols of fertility.

If your honor drops to zero (honor is indicated by the bar in the bottom of the screen) the game is over. The honor will decrease if there are archeologists touching the golden idols.

Arrow keys will move the boulder.

Esc - will quit the game.
Alt + F4 - Will quit the game.
Alt + enter - Will toggle fullscreen.

    Hey Petri, sorry if you didn’t want the game to be posted about earlier than now. I assumed the Assembly competition was a separate thing and had nothing to do with your monthly games. That, and it’s hard to pass up writing about a game that involves squishing people under a rock capable of conscious thought. Also, up above you spelled “the2bears” as “the2beards” by accident.

    Did you ever consider making it so the ragdoll guys hurt each other when they collide together? It would be cool to see a chain reaction caused by the boulder flinging an archaeologist into a heap of people.

  4. futuramaguy42 Says:

    This game is amazing. The ragdolls are great. Its so fun. Keep up the great work.

  5. petri.purho Says:

    Thanks everybody for the quick comments. As I stated in the quick edit, I’m right now in France and I had the game on automatic publish, so I totally missed the missing download link.

    Big thanks Nick for providing the mirror.

    And Jared, don’t worry about the blog post. I’m glad you posted it earlier. I’m still amazed on your ability to find freeware games so quickly. It’s amazing.

  6. Nathan Ostgard Says:

    Wow. Just amazing. Lovely choice in music, too.

  7. Crow Says:

    First it’s really easy, then all of a sudden it’s like ants on a candy. Super fast ants. Getting to the upper levels is tricky.

  8. red_forman Says:

    First impression: the sound of rolling boulder as well as screams and behavior of the ragdoll archaeologists - these are definitely the things that make this game JUICY :]

    Thanks Petri!

  9. Andy Says:

    Does the gravity seem a bit weird to anyone else? It’s hard to jump quickly up the small platforms. The boulder seems to stick.
    Fun game though. Thanks.

  10. Crow Says:

    Yeah, that’s what I meant when I Said it’s hard to get to the upper levels. The boulder either sticks to the center circle thing, or usually just falls off.

  11. Decipher Says:

    Aye, my turn. As a scener, I’m damn grateful to see Petri, in one of our compos. First of all, I loved the rag-doll concept, especially crushing them with a boulder :) . Also I know how this thing came out in three days, so I respect the work ultimately. So here’re my cropped critiques :

    1. The more rag-dolls are there the more slower the game is, so how about applying rag-doll physics where it’s needed? For example, while the guy is walking, it won’t need rag-doll physics until a collision with the boulder happens, or until the guy jumps to death.

    2. Petri you already know this one :) , it’s not visually eye-candy’esque, to see the guys trying to climb upper and upper when they do reach the relics.

    That’s all, other than that it’s an immensely adorable, guy-crushing game!
    Erittäin hyvä peli ;)

  12. robolee Says:

    impossible. the boulder is too responsive

  13. Petri Purho Says:

    Thanks everybody for the nice comments and thanks for the critique.

    The controls are bit difficult to get a hang off. The jumping could work a bit better (at least with the center round pellet thing).

    @Decipher: Actually the rag doll physics are only enabled after the boulder hits a guy. The reason why it slows down with multiple jones is probably SDL. The software rendering is just damn slow stuff.

  14. Alex Says:


    I really like the graphics in this one, I love the rag doll effect when you start to run guys over. The speech bubbles from the statues was a good touch.

    The sounds are ok. The bones crunching when you roll over a guy is great. The screams could have sounded a bit more painful I felt.

    The music is a bit odd for this. It is very calm for a game about crushing people to death with a rock.

    The game play is ok. Hopping the bolder around the first two ladder to scare the guy into a big group so you can sneak around the side and roll over them is fun. The top half I found a little too tricky to get my boulder into so the playable area was cut a bit for me.

    The game play does not seem as addictive as some of the others. I think this is becuase my favorite two crayon physics and TAGD both had a goal to aim for. Where this time you seem to squish people untill you eventualy fail to squish them all.

    The time scale and quality of the games you have made is amazing. I all ways look forward to seeing what you come up with next.

  15. CaRteR Says:

    I really wanted the archaeologists to win, so that the secrets of ancient civilizations would not be lost from the human family in the mists of time.

  16. Jae Says:

    Nice work, can’t wait until your next game comes out. :D

  18. Petri Purho Says:

    @Alex: Thanks for your constructive feedback. It’s a good point you made about Rolling Boulder missing a definite goal. It’s probably one the reasons why the game doesn’t feel really all that compelling.

    Also I think the game way too difficult. So it has quite a big learning curve.

    Hi there!
    I’ve just returnd from hollydays, so I can navigate again. Just a few words, for it is already late :
    -this game was really fun and quite popular among young children(I managed to download it using a 56k connection and I showed it to some people)
    -It was very entertaining, though not as addictive as Crayon Physics(by the way I created another level but I didn’t have the time to release it until now, I’ll post it tomorrow)
    -I scored 26 millions (I don’t think somebody has ever raised this topic)
    -I only played Tafb once because I downloaded both games at the same time. The rolling boulder was way more entertaining…..
    -keep up with the good work!

  24. petri.purho Says:

    @logr: Thanks for the feedback. It’s always nice to hear from you. (I’ll try your new Crayon Physics level tomorrow).

    It’s funny to know that the game was a hit with the young audience. Children always seem to like when they get to kill a lot people in imaginative ways :D

  31. House of Payne Says:

    I could not figure out any way to get the boulder up to the higher platforms. Once I let one Jones up to molest the idol, the game was lost because I could not get up there to stop him. How is this done? I can jump up to that stupid pellet thing in the middle, sometimes. But I can’t jump any higher than that.

  32. Shawn Says:

    As an archaeologist with an interest in games, I LOVE this game. Well done! I imagine my colleagues each time I roll on through… good for my mental health!

    Keep up the good work!

  33. wintermute Says:

    i also can’t jump any higher than that stupid pellet thing.arrgh. i suck at games

  34. Twad Says:

    Quite fun until the dudes get faster than us.

    The game would be funnier if we could have a way to get up that doesnt require luck, glitch use and long training to control the boulder.

    I wish we had a simple “Cant lose, just having fun” mode/code/whatever.. i just want to send them flying them for hours.

    Dying and “retrying” doesnt reset the victims speed, and after a little while or retries, they get so fast they basically teleport and make massive jumps everywhere.

  35. david Says:

    how do you get to the top right half petri

  36. david Says:

    how do you get to the top right

  37. david Says:

    you should give it a sequel. because number one it has very good ragdoll physics number two i play it for hours number three it helps the wait for your connction but here comes the cons it is impossible to get to the top right also maybe you can make the rolling boulder a person so you can punch the people oh yeah and if it was a person you could make it a city scene and make the idols important people and make the archaelogists assassins and you can add funny parts

  39. SMB Says:

    To get to the top right, don’t try to stop and jump on the tiny block; just roll over it and you should have enough speed to get to the edge of the platform and cling; then jump up.

  40. SMB Says:

    I’m finally got to where I can move between the two statues quickly enough to survive for a very long time. I just got about 3.3 million points (after about five minutes, one slip could mean game over…). I wanted to do a ctrl-print screen to save my high score and it restarted the game, so I don’t know my exact score >.>

    My strategy is to clean off the right statue and fall down the ladders on the right to clean all the CPUs off the right route, then jump up to the left statue and clean it off. Then I jump over to the next to highest platform under the left statue and roll back and forth, racking up points (this only works when the screen is full of CPUs), until the right statue gets attacked again.

    Most of my slip-ups occur when a ton of bodies are clinging to the rock, making it hard to jump.

  41. Green's mom Says:

    My son loves this game. He just scored 5,403,500 points. He’s 4 years old. I typically get 1500 points, so he doesn’t get it from me.
    He keeps asking me how he gets on to the next level…
