Really cool game ! The music and the ambience was really cool. I struggled a bit with the double jump, having to quickly press up twice is a bit weird when you are also trying to move horizontally with the same hand, I wish space was jump instead of the reset to checkpoint button. It also took me some time to understand the flip upgrade, at first I though that boxes telling me I could not flip were actually boxes I could build with my newfound power and since there was a lot of overlap in the zone after I unlock the power it wasnt very obvious and I ended up being lucky after mashing for a while.
That being said, it was fun and I reached the end, I hope you win 💪
