Great game, don't abandon this concept!
I really love this game, and I also love your level design. It's just difficult enough that I don't get frustrated playing it, and it is very easy to get into. This has to be my favorite flash physics game ever. The simplicity of design, gameplay and the level size makes for a fantastic game. I'll be watching your work for quite some time, and I think it would be great idea to take the engine you've created and come up with a sequel with many more levels, maybe even a hundred or so. Hell, I could see you selling this game if you created enough quality levels for it. I know I would buy it.
Thanks for the quality entertainment! Newgrounds is where it's at!!
