Someone should port it to the iPod Touch/iPhone.

This would be EXCELLENT, and I'm sure would run great. I don't think that it's open source, though there IS a Mac OS X version out there somewhere. This would be fantastic, since theres really only 8 buttons used or so.

It is not open source, but the creator of the game (Pixel) gives the source occasionally to skilled people requesting it for a port. I got the full source code that way and was able to port it to the GP2X.
So, if anyone is willing to port this to the iPhone, just ask Pixel for the source code. Mail is rochet at nifty dot com. Maybe send a demo along to prove your skills.

Never heard of the game, but it looks really fun.
