Might I say that this game has a very solid structure and design. The graphics are rather good for the intended look, and the game-play itself is great. The only flaws I see is the lack of upgrades, the effectiveness of the current upgrades, the need to refresh after each death, and the variety of enemies. Other than those few minor problems, the game is awesome. 4/5 in my opinion, and if you manage to update(not create a new one as that would lose all credits) the current version it would be 5/5.
WTF!? I started level seven and it was going normally then, out of NOWHERE, a penguin FLIES across the screen! PENGUINS DON'T FLY! It freaked me out! Pretty funny though...
