I always love seeing other Godot games in game jams! This played like a speed run through a Metroidvania. It was a really interesting concept. The controls felt really good on a controller.
My biggest complaint was the music. It was so strident at parts and so loud that it interrupted my concentration - and since timing the jumps and dash was difficult enough, I sometimes just waited for it to be over before moving again. The levels themselves were very punishing, and it took a lot of replays to get through each section after the first couple lanterns. One missed jump meant starting all over and that ruined my enjoyment after a while. I think it has a lot of potential though.
Really nice start.
