I am so glad that you finished the game and r-submitted it. I had almost forgot about it's existance. I have noticed two bugs still in the game.
1. Feeding, sometimes the food won't stop moving after hitting the ground or go flying off in some random direction at enormous speeds. Neither of these seems to affect gameplay too much.
2. While training swimming you can occasionally get additional boosts up and down.. These slingshot you back and forth for an extended period of time. Before discovering the bug I think my max distance swimming was something on the order of 10,000. After (and i didn't play with it much) I got over 91,000. And I didn't even have to press a key to do it from 2000 on up.
Other than that fun game, cute game. Much improvement from the last version.
