Stellar Game! Great idea to have players "race" each other. Very impressive to keep track of all those races. Great map with a lot to do and places to go. Everything was intuitive and you had good ui so I could find out what was happening.
I'd love to see who has beaten my race, but know there's a time constraint to do everything for game jam.
A small tweak would be making the swimming controls feel a bit better? I felt like I was constantly being thrust up to the surface and felt out of control when moving.
Overall great work!
