Ok this is definitely the best game idea I have seen in this jam until now. The sheer amount of possibilities with just keys on your keyboard being physics boxes is insane. Almost reminds me of Q remastered. This isn't fitting the theme of the jam really well but I don't think it matter when the outcome is this wonderful. Also, the keyboard puns are great.
I know it isn't much noticeable but the amount of polish you have added in 48 hours is nothing to laugh at. With a few more levels added, it might as well be a demo for the final game.
Great job and I would love to see this made into a complete game I can purchase!
