This is awesome. The art style is the silliest in the jam by far. I love the uniqueness. ost and sfx are also perfect. But the first stage is a bit punishing, I think the player movement being slippery is intentional and it's fun to control but the enemies can be a bit tricky to dodge since they move so fast. I had an amazing time fighting the boss. Also look into it a bit why Gerald is jittering while moving. The common source of bug is putting movement logic/physic logic/camera logic separated in Update() and FixedUpdate().
Than you so much! Yes many people have commented about the first stage being too punishing and I agree. That is something i will take into account next time. I think the jittering came from the camera since I had to choose a different approach to the camera following the player than just parenting it. Thank you again for your helpful feedback!
