The only submission that I have come across that feels like a legitimate finished project. The art style, sound effect implementation and balance to the game all make me feel like this could have been a year long project never mind something created within the time frame. This is definitely my vote for number one of the year, I can only urge people more to try it and give their own feedback on their own experience.
Also it actually has a high score board so try beat me before you disagree - TDC
