The idea isn't bad. But either I’m missing something, or level 4 is impossible to beat—unless you manage to hit the exact pixel needed to jump off the wall. It’s just not possible to land on the platform. By the way, the restart button doesn’t work either
So that’s how it is—the upward dash mechanic is really unintuitive and hardly ever appears anywhere. I’d figured out the level structure, but my theories—that the protagonist jumps higher when fully charged, or that you could climb up using pixel-perfect wall jumps—turned out to be wrong; it’s just an upward dash, hahaha
