This is the makings of an interesting puzzle game, if anything. Let me give my thoughts,
You've definitely put some effort into the art and that is to be commended. It's quite servicable and lends a style to it. If you pat out some more polish to it, it could look great!
Simple, grid-like puzzle game where you choose different characters and try to find the best route. I think it needs some stickier game loop, but it's a place to start.
My biggest gripe is really just the amount of words on the character selection. The tutorial for the first character is well appreciated and done well, but going for different characters makes it hard to switch because you have to learn so many new things about how they move, it becomes a bit tiring.
