Very nice entry. The art, sound effects and music go really well together. It felt a little unforgiving as to whether the player would fall in the water but I guess it's something to get used to. I agree with Grisgam about the boxes respawning too soon. Otherwise the physics feels good, the penguin is very cute! I don't know if it's a bug or a "random feature" but I quite like how the boxes sometimes slide into position when they respawn.
