Ok, first of all I want to say that this game is awesome. The mechanics are like any other game, but tweaked just right so it's original. I love how you can find different penguin levels, and i'm currently trying to get one of each. However, sometimes the penguins do get stuck behind bushes. It gets a little annoying when i'm on the last turtle. Meh, the fourth turtle makes the game easy in the jungle!
Nice game, it has better animation than my games. One thing I might suggest is less expensive items. Maybe you could also make unique attacks for each enemy! actually heck I don't know i've only seen the first 3 enemies
