I really wanted to get deeper into this game, but I struggled with the tutorial and wasn't able to figure out how to advance through it. It seems like a very ambitious project. I can't believe you got multiplayer support into this thing in the two week constraint.
But I would say the ambition is part of the reason why I couldn't get through the tutorial. There is so much depth and complexity that you have to explain, and it's hard to fit that into the 64x64. A game like this requires a very long tutorial or series of tutorial challenges, and that's the sort of thing that just takes more than two weeks to do well.
