Awesome! Thanks for replying on Twitter!
I think across the board it was pretty hard after the intro level. It's mainly the "aerial" aspect of the levels that gave me trouble. The timing with some of the controls was very specific (like if I missed an action I feel down and had to redo 3 more previous steps to try again).
Though as a whole this isn't a completely bad thing I did end up playing for 10-20 minutes getting that "must complete level" flow going XD
If anything I think it'd be more about ramping the difficulty a little more smoothly so players have time to learn/succeed a bit before they experience multiple fails (these generally happened when it involved swinging with a cactus enemy on a nearby ledge I needed to land on though you might have a way to solve for this I just couldn't figure out)
