I like it! I sat through a whole play through that felt a little excessive. I think a smaller board would have made me contemplate my moves a little harder, the space requirement wasn't really an issue through the whole game, it felt more like racing the clock, which is good! I think constraining the space would have been a welcoming addition of stress, if you know what I mean ;)
Puzzle games are hard to nail down because they are super simple, but a bad puzzle simply won't do. I don't think this was one of those bad puzzles. Good job :D
