Thanks a lot! Will definitely watch the video later.
I'm positively surprised that someone is actually playing this on expert mode so kudos on that, clearly you're not a first-timer with this kind of games haha. The third boss can be quite challenging on the expert mode but otherwise it's not going to be too hard if you wish to finish the game. I didn't mention this earlier but I built all the levels in three days so yeah they're not perfect, definitely needed some recognizable landmarks and checkpoints closer to the upgrades. Glad that you remembered where to backtrack after getting the boots, I was worried that people might not realize where they have to go from there. I didn't think of adding W as a jump button but will do that in an update after the jam, space just feels like the most natural choice for me.
