This was absolutely stunning! I loved the worldbuilding (hints at a very well-built lore, and questions about how moral the stars truly are), the mechanics (the platforming was super smooth, and I loved the gradual introduction of more features)! The music is also some of (if not the strongest) music I have heard in a spectacularly long time: I would totally listen to the full soundtrack if released online!
All in all: An incredible journey, and congratulations on finishing such a momentous work in time for the game jam! I don’t try to say this often, but this really does have an incredible amount of potential. Well done!
