Love the spore vibe, the minimalistic player and enemy graphics and the many great ideas you put into the game. The fact that the world is limited is much better than just swimming in a huge ocean and gives it a puzzle aspect, which I like very much. Regarding you only worked 3 days on it, the results are astonishing. My only criticism, I don't like the gray level border / stones too much, maybe making them transparent and let the wobbly blue water background shine through will look nicer.
