i just finished this the other day after sitting on it for like a year or more and i wish i'd played it sooner. i've been craving something to scratch the same itch as pseudoregalia's rich movement system, and this game absolutely does that and then some. i think things are a little floatier than i'd like and some encounters would really benefit from a fixed camera and fewer enemies, but those are pretty minor gripes. it's much fun just to run and fly around this little island, and it feels like you put a lot of thought into designing the challenges.
i even enjoyed the final boss fight! and i usually hate boss fights. but you really capped it off with a big, flashy, fun as fuck sequence that builds on everything i'd been practicing from the start.
i'm also impressed at how robust the physics are. i never clipped through anything (my specialty, something i am infamous for), only managed to get myself stuck once, and aside from camera frustrations i never really felt like it was the game's fault when i failed. props to your play tester too, because they must have been thorough.
fantastic work all around. i mean this as a compliment: i wish this game was longer.
