It's a cool concept, but the UI could use some work.
There's a couple of things that stand out as possible fixes to me:
• the info about mint doing anything is only starting to be apparent in the first jumping levels. Before that it's not even a thing in the game (as the walls block the movement). It doesn't help that you have to scroll a text box to read about this.
• You have no idea what the flame thing does at first, you have to fail a level to find out,
Other than that, a really fresh (hehe) idea for a game! Great work!
