Nancy

Not to be a Negative Nancy, but the sound was out of sync during the final scenes.

Also, great idea, but not so amazing performance ;)

Splendid animations, tho, enjoyed those ^^

There's an issue regarding the physics of the game (never forget that the game has to ~feel~ real).
You're merely decreasing the time between the ticks? (The hamster's turn-ability wasn't affected by it's speed).

+1 for the custom graphics; it has a decent feel to it
+ 1/2 for managing to make polygonal hitboxes

Keep at it; practice makes perfect! (Just never forget the ~feel~)

Good idea, lousy performed

Try adding some way to gain blues, for starters..

The blues could determine how high the bat can fly: when you grow, you can fly higher.

Also, buff the falling-speed of the green goo he shoots out, and add some hell-holes or something where you can feed to regain greens.

Great graphics and idea, as said. 5/10 & 2/5 rated.
Don't just leave the game be, buff it up ;)

Cheers
