This was fun. The controls felt really good. I managed to not hit any penguins on my first run so I went back and tried. I wish I could back through more penguins without losing as much speed but I'm guessing they are there as something to avoid and not something to play with :). I did have some trouble spotting the UI on the main menu and in the game after I full screened. I assume this was because of the UI is Real wildcard but I would probably make your main menu buttons pop more and the UI a bit bigger post jam if you are going to tweak things :).
awesome job
