Aww, thank you so much :)
So what you described as the "main loop" isn't actually the loop mechanic of the game (which is flipping the level when you reach the top) but it was indeed designed in a way so you'd learn shortcuts and exploits/skips to get faster and faster, I tried my best to make (almost) every modular piece have multiple angles to approach from, so when constructing the level (and of course how the level sections connect) they'd be plenty of skips you could do once you get the teleporting! If I had the chance to go back in time I'd probably make the indicator of where you'll land when teleporting WAY better instead of checkpoints as I think that made things much harder for people (but checkpoints could work for sure but maybe only one halfway up or something).
Really appreciate the effort you put into your comment, it means a lot! Thank you for being so kind despite the present issues :)
