I understand. Streamers may be better than average. I don't say your game is too difficult i think it's good to have this challenge. I just say that it miss a reward for noobs like me. Just a first reward to help being engaged with your game.
okay in fact i give it another try and i found why i was strugling. For the first big jump i was waiting for the top of the curve arc to do the second jump and my velocity was almost 0 so i don't jump higher. That's why i'm stuck.
