I really really really really REALLY liked this game. I played for an unreasonably long amount of time. I am very glad you posted solutions in the comments because a couple of the puzzles were really hurting my head but all of the solutions felt clever. I spent an UPSETTING amount of time on level 12 before sadly giving up on it. My only suggestion is that it might help to have some kind of preview of what will happen to a number so I don't have to sit through the animations every time I want to test a theory, but apart from that this is excellent. I would love to see this game turned into a full release! If this doesn't get featured I will be shocked.
