Yeah the game is 100% going for the Jump King/Getting-Over-It type feel.
With the first 4 rooms I was going for something super simple, but easy to mess up, where by the time you make it to the top of that section. you've fallen enough that you're disciplined enough in the mechanics to continue onward.
Thank you for mentioning the thing with the back button in the option menu, have no idea why I didn't think of that lol, also your critiques weren't that harsh, I've been shit on way worse before.
