Hi! The idea is good, the implementation isn't perfect. I mean, it is fun to play for a bit. The main problem, I think, is the feedback of how long you need to make the characters 'work'. And besides, the tutorial is quite straightforward about left-clicking and right-clicking on the characters, it doesn't say anything about the little arrow and its meaning.
Anyway, it is a good game, and you pulled it off all by yourself, and that's a great accomplishment inf my opinion!
Great work!
