Hi, thanks for the honest feedback. The jumping is more or less HeartBeast's algorithm, I just played a bit with the constants.
The R key was explained in the second level that has colors. That's the only place where I deliberately lured the player into taking the wrong color, so they learn about restarting. Maybe my trap didn't work on you, so you didn't see the hint 🤔
I think I will have to rework some levels, so I don't frustrate the player too much. But the way up is intentionally red: if you could get up there you wouldn't need to hop the platforms at all. I will have to think of something, maybe a safety net in the level or a rewind mechanic in the game? Make every color item a checkpoint?
Good thing you liked the intro, I noticed after submitting, that I didn't build in a skip function 😉
