It was weak.
The concept for the game is a foolproof one -- the maze. You made a good, slippery physics system to up the ante, and best yet, I couldn't do the "right-click cheat" where I can go through walls by simply right clicking (though I could skip entire levels by right clicking and pressing "Play").
Where the game fell down was two places -- the lack of sound in the game (none at all, even for background music), and the ugly graphics (if the block had been one solid color, it would've looked better than being the rainbow). The black walls also seemed somewhat drab -- you should try to focus on the artwork as much as the game itself and how it works. An ugly working game is almost as bad (but not as bad) as a beautiful glitched one.
So, you'll work it out -- I have faith in you.
G'luck!
