Really fun. The gameplay concept, as well as the story, are very interesting, and the execution is really nice, with such surprisingly tight controls that make it seem like the player character knows what button you're going to press next. I suppose, thematically, that actually really fits lmao
I do have one suggestion, though. Perhaps change the music player from an AudioStreamPlayer2D to a regular AudioStreamPlayer. It was rather distracting for me, with headphones on, to hear the directional music coming at me from different angles as I went through the levels, fading in and out depending on the distance to the start.
