Thanks for the feedback! :)
Yes, the hitboxes bothered me too but after playtesting the levels a bunch of times I got used to them so I ended up forgetting to fix them. Gotta make them more fair.
For the first moonwalk level I just realized that it's actually bugged from someone posting a video (there's supposed to be 2 tutorials on that level, but the first one doesn't appear in the web version!)
