Really cool game, very impressive for your first game jam! How much experience do you guys have in Unreal Engine in general? Mind if I ask how your animation and collision works? Is that procedural animation on your player? I've never had my skeletal meshes respond that well to the environment, I'm really interested in this :D
Definitely well done, the physics are fun, dive mechanic is super fun, and the increasing difficulty really hits the spot. I'm impressed :D
