I really enjoyed this but I had to use a remapping app so I could play (mostly) with gamepad; it was practically impossible for me to play with a keyboard. I suggest is to make the spike collision smaller. There's on article on how Celeste (and others) actually have smaller collision than the hazard which makes it much more forgiving and feels a lot more fair; as is you can die but it sometimes it doesn't even look like it overlaps. Also some indicator on the charge level would have been helpful, and maybe resetting it after changing? I died several times early on because I had just dashed, then change and went to float but plummeted to my death. There were a few other bugs, but overall really great design, even if it did end up being too challenging for me (I stopped at the level with all the platforms with just one or two spikes, maybe 10?). Keep up the good work!
