For a first attempt at game development, this isn't half bad! Although the art is pretty rough around the edges, I do quite like the aesthetic, it's nothing if not cohesive. Of course, some sprites had issues with existing in squares rather than being transparent, but that's something that could easily be cleaned up. I was a little confused on how to play at first, but I got there eventually through experimentation. I think some music and sound would go a long way
