Well done! I really loved the art, from the backgrounds to the characters and their animations. I think you did a great job animating them in ways that give them some fun and personality (kudos for the butt-view when opening the door haha got a laugh from me). Definitely simple mechanically but for sure something that you could easily build on, a great foundation! My one gripe is I wish the movement was a bit faster since it could be sort of tedious. But overall, great job!
