That was cool! It felt quite polished in terms of the visuals and feel, but there are a couple issues I had with it. Overall, i feel you did a good job teaching mechanics through game play, but when it gets to the more complex ones (whatever it is that the blue guy does), It doesn't come as intuitively. Also, as I'm sure you have heard before, I found the belch timer a little annoying to have to wait for.
Other then that though, it was a fun game. Nice job!
