Lovely game. I can tell a lot of creativity and thought went into the mechanics, they are clever and leave a lot of room for complexity. I love the pixel art (your thumbnail is amazing) and the sound effects. The aspect ratio seemed a little off on my browser at first, but it didn't affect my game play as far as I could tell.
Anyway, a really cute and creative game, I'm glad to hear you'll be continuing the project. Great job!
