The concept here is pretty interesting, which is funny given how not-proud of it you are, and the execution is surprisingly fun for a game that's basically just math.
Though, I think the elevators could use a bit of work - Sometimes I got caught on the elevator by rushing too much and it left without me, which wasted a lot of time in a way that wasn't really that fun.
Overall, it's a good game, and could honestly be really solid with a bit more polish.
