This game is the real rage bait!! I still stuck to it but couldn't make it past level 4 haha!
My feedback might come from my skill issue, but I'll say it anyway! I think you should implement coyote time, or if there is, maybe a little less punishing. There were a lot of times that I saw I made the jump, but I actually didn't, and I get the whole point of the game is to kill you in annoying ways but its much cooler to die because there was a twist you could have never guessed, than because the game didn't read you pressing space. This is a techinque celeste uses and that's why it gets to be so hard but so fun at the same time!
Still I loved the rage bait and If I didn't want to test other games, I would play it longer. Good job!
