Thank you! Yeah, I don't think I ever got the difficulty quite right, despite my spending pretty much the entirety of the 4th day playtesting and tweaking it. I wanted it to be hard enough that beating it for the first time felt like an accomplishment, but I may have gone too far and made it more frustrating for a lot of players instead.
Good rule of thumb is "If the developer thinks it's hard? It's too hard. If the developer thinks it's easy? It's probably just right".
I did the platforming sections in our game using that philosophy, making things honestly probably too easy? (I leaned much more on the side of easy). But then there are sections like the downward mushroom that people are still struggling with, despite that being something I thought was just challenging enough y'kno!
