This is an incredible game! You can definately tell that 4 people worked hard to get the game to this level of quality in 10 days. Not only that, but every aspect of the game melds together so well to create a complete experience. If this is the first time you guys have made a game together, I couldn't tell. The teamwork definately shows. I can understand that the difficulty might not be quite some people's cup of tea, but I believe it's a perfect balance of seeing new mechanics and being able to deal with the previous mechanics at the same time.
I had a lot of fun playing, I could definitely see this game becoming something people would pay $10 if the idea was expanded upon.
