First off, not a game dev.
I'm afraid I had no idea whatsoever what I was doing in this game, and the lack of instructions, and lack of access to more modes of play made that impossible. It looks like it has great potential, but I'm not really quite sure of what it is, or what I'm supposed to do. I think if you were to add some instructions, the "Enjoyable" score would go from one star to at least four.
