The game might need tutorial. Its concept is very simple (press space at the right time to stop at the right floor), but it took me a while to figure it out. The first line of the instructions on the bottom-right got me very confused, I thought it was the first thing I had to do, go to B at 19:00, when actually this comes at the very end.
But once I got the rules, it works pretty well. Can be a little bit frustrating at time, but succeeding to reach a floor is satisfying. I’m not sure there is a use to the money we earn? The game might need something more to be less repetitive. It has a good premise though. It’s certainly a system I can imagine be rewarding to master!
