there's a useless box at lvl 9 and a bug at lvl 10 when you go backward, but it's a great game. well done!
Did you really manage to found a way to solve it with only 2 boxes?
No way! That would mean you found a way that I wasn't aware of, while I made the game. You must be really clever!
Needs more content, down arrow mechanic is only used once.
Wish there was more
Actually, this is really good! It's nice to see something simple, yet good like this nowadays.
