Not only do I highly believe this game is stolen, I know for fact that the background music is from the TNMT: Turtles in Time game on SNES. So double stolen.
I agree with most everyone, a very good start. Now all your lacking is some twists, different modes of play and maybe a point system. I can't say much though, I couldn't do any of this.
Aye, Obeliskos, I've played this game on their main site and loved it. Sadly, this is only a demo. I'll have to give it a 3/5, but that's the best I can do for any demo on this site.
