I played the post-jam fix and enjoyed it thoroughly. I dug the simple strummin' soundtrack, the art style, and the off-beat humour of the intro/outro. It is an excellent proof of concept! The most needed area for improvement is the instructions. I actually typed a comment about how the game was unplayable before finally figuring out that I had to drag the mouse from one side of the tile to the other. That was not obvious. With a clearer explanation and more responsive feedback, this could be successful.
