As someone's already said, it's tough to rate an MP game with no-one else joining/hosting. Honestly, I was incredibly unsure about what I was supposed to do. Reading that the game is 'totally based on luck' doesn't fill me with confidence, either - what's the point in gameplay if luck is the only deciding factor? You might as well just flip a coin. Not trying to be a downer - you made a game in 48 hours and that's always incredible :)
