I'm creating a game and in the name I want to include an adjective that shows something that increases in difficulty. The problem is that I don't have that great of a vocabulary and the internet didn't seem to help. I don't even think there is such a word that can explain that. If there is no such word than I would appreciate it if you gave me words that have a similar meaning to what I am asking for.

You could describe the game as having progressive difficulty.
