I used to have the same problem. I startted many many game projects and never finished any one of them. And I still do that, but now a days I have to finish the game by end of the month I hope you give rapid game prototyping a shot and finish the game even if it turns out to be a crappy one. And let me know how it turned out (send me an email with download link).

The song that inspired Jimmy’s Lost His Marbles was PeeWee Herman Theme by Mr. Bungles. It’s a cover of the film’s main theme.

Love the blog, and am really impressed with what your doing.
As someone whose started about 7 games over the last year or two and
finished none of them, your a bit of an inpiration.
Just out of interest, what was the song that inspired the game?
Was it happy coloured marbles by ween???
If so you’re doubly cool!!

For Marbles I actually used a home made 2D game engine. I don’t think it saved much time, because during the development of Marbles I ended up fixing some bugs in engine. I probably could have coded marbles in two days, if I wouldn’t have used my own game engine :).

Torque Game Builder would be a excelent platform to do experimental games. I know there are some that are done with Macromedia Flash, Game Maker and atleast one done with plain HTML. I think its important to select a development platform for your game that you feel confident working with. And most importantly select a platform that can be used to do the game. I don’t think Troy would have been all that cool game if it was coded in C++.
