Loved this game, it's so clever. And it looks super good, I really liked the scribbly graphics. I think I was lucky in that I unlocked one of the abilities pretty quick by accident so I understood the map mechanic pretty fast because of that, but I think I could see people not realizing it and getting frustrated a bit, but still a really cool concept.
Biggest nitpick would be that I'm not sure if I would consider this a metroidvania, despite being an incredible and very polished little puzzle box platformer (specially for a jam).
