My April Fools’ joke worked like a charm. The Divorce managed to fool some of my regular readers, most notably Bill of, who actually blogged about it 🙂 And I also got an much needed extra day of development for the Forbidden.exe.

So here’s my real 8th done-in-under-7-days experimental game, which is a bit different from my usual style. It’s an experimental horror game. So be warned, there’s harsh language, violence and other fun forms of violation. One could say that it’s an experimental violation game.

The idea for the gameplay came from my talks with Daniel Benmergui at the GDC. After the Nuances of Design session, we talked about the idea creating a game (for the Eerie Horror Film Fest), where the gameplay would communicate that feeling that you get from watching a good suspense / horror movie. So here’s a elaborate prototype of that idea.

    So I guess you actually used eight days? Shame on you! joking aside, the game’s friggin’ hard!

    The gameplay isn’t to original, although it is different from others of the genre. It’s fun, but not nearly as fun as some of your other games, such as Pluto Strikes Back! or Cacodemon’s Barbecue Party in Hell. Nonetheless, good work.


  3. petri.purho Says:

    Please don’t tell anyone I used eight days. My reputation is gone if people find out.

    Seriously, including the one extra the game toke 6 days to complete, so over all it’s still done in under a week 🙂

    I was a little afraid that the game would end up being too hard. Sadly it seems to be the case. I do my own graphics with a mouse so I probably have a better eye-mouse-coordination than the average guy, but I it’s not depressingly difficult.

    (by the way, thanks for writing the Pluto Strikes Back -article 🙂

  4. Joel Button Says:

    Maybe you could control the orb with the arrow keys or WASD instead?

    Also, the first time I played it, it was without sound, (on a school computer.) When I got home, I transferred the game to my computer, and played it with sound. It scared the crap out of me! Resident Evil pales in comparison to this! Actually, I guess Dave is sort of like Nemesis in Resident Evil 3.

  5. petri.purho Says:

    Thanks for the compliments. Brainsaw’s music really adds a lot to the game’s atmosphere.

  6. Exilberliner Says:

    Great game as allways. I liked the storyline and the really deep developed NPCs 😉
    And I personally do not find the game to hard.

    Oh, there is a bug in the .txt-file-level, when you hide at your startingposition you get ‘teleported’ to the file-cage entrance after they get killed.

  7. petri.purho Says:

    Thanks Exilberliner.

    It’s also the mouse that plays a huge part on the difficulty of the game. If you have a crappy mouse (or you set it up to be very quick) the game is probably impossible to play.

    I noticed that there seems to be some kind of random teleportation bug, that happens sometimes after the dialog window is closed.

  8. Mr. George Spagethi Says:

    I was just about to crap my pants everytime that Dave -guy screamed and tried to eat my ball. This game creeps me. Funny storyline, nice graphics and sounds & “music” were awesome! All in one, this is a freaking cool game!

    BTW. What are those balls?.. o_O

  9. petri.purho Says:

    Thanks Mr. Spagethi for your kind words. I’m glad my game creeped you out. I really don’t have a good answer to the question about the balls 🙂 I put them there originally as place holders. I then tried to create a nice horror themed icon for the bad guy (it was a Jason style hockey mask), but it just looked like crap, so I kept the balls.

  10. ismellawumpus Says:

    Ha! At first I thought “Oh another maze don’t touch the edges game” But the _feel_ was much different. I guess you hit on some base instinctual elements because my daughter (age 5) screamed upon hearing that horrible “scream” sound and seeing the ball chase me. Good job at setting the mood! I liked the “trapped in someone’s psyche” feel it had. Transformed the game. I really like it. Doesn’t work well on a touchpad though 🙂

  11. localGhost Says:

    Very atmosperic, bravo!

    Was not too hard for me, i needed to replay on three levels for total of only 5 times or so. But my coordination is above average definitely. Maybe worth trying once more 🙂

    There’s a typo on one of last levels: sentence with two “the”, while first “the” should be “to”. I managed to forget the sentence itself already :/

    P.S. And yes, i believed your 1st April joke 😀

  12. petri.purho Says:

    @ismellawumpu: Huge thanks for writing the critique on my games. I’m sorry but at the moment I’m at a convention, so I cannot give you more detailed response. I’ll give you a proper response on Tuesday, when I get back to my normal way of living.

    @localGhost: Thanks for the feedback and for pointing out the typo. I’ll try to fix that one. I think your one of many who fell for my April Fools’ joke 😀

  13. Nikita Mikros Says:

    Wasn’t sure what to expect but this was really well done. I mean, it was just a black ball but it felt… dare i say it? scary… i didn’t think the mouse control was a problem, seemed pretty natural (if frustrating when I hit the edges)

  14. Decipher Says:

    Phew… That was a real pain in the arse. Especially when I saw Firefox being destroyed I felt kinda sorry for it, but hey still Opera is the best! 🙂

    Well the game is damn hard. Really, and I know that I haven’t posted some comments to this blog lately but when you had to deal with a Linux it really gets annoying. Whatever, you should really easen the game. And I remarked something pricky, the IE logo has a higher Z-order (or a lower drawing order) than the one of the < hero >

    Finally, I admit that I couldn’t stand against that annoying boost sound which makes me ike and feel frightened.

    Again, a perfect game!

  15. Starky Says:

    I liked Forbidden.exe very much, as most of your experimental games. I appreciate mostly the idea, funny storyline and nice presentation. The game was pretty easy to me, I had to repeat some level approximately 3 or 4 times at all, so I think the difficulty is OK. The gameplay itself wasn’t very exciting but it’s understandable, due to time limit of one week.

    Keep up the good work!

  16. Joysticker Says:

    Fantastic. Great idea.

  17. Jhon Says:

    I’m wondering why I was afraid even if I knew the game would do nothing to my computer… well, the concept just worked ^^ great music also.

  18. Trevor Says:

    Nice game, great idea. Reminded me of Maeda:

    I like yours better, but the execution on Maeda is done well too. And if you wanted to make it even more terrifying, you could have that floating graphic be a grab of their actual directory listing… that would be evil 😀 Nice to see you have FreeOrion btw 🙂

  19. ascidus Says:

    Love it….
    And I love the SHODAN quote in the background :]

  20. Philip Says:

    Wow! I was screaming each time i hit one of the walls and dave was coming for me 😀 even some of the ppl who lived came to see what game it was.

    only difference could have been that the game really would have deleted 1 or 2 files on my computer 😛

    Also, this game gives me the creeps (in a good way)!

    Yes, I am a chicken.

    it’s amazing that such a simple game can creep me out so much. i was totally scared of that damn black orb!

    jumped in my seat twice playing it through!

    great job.
