Halcyon

You find yourself in calm depths of the ocean. You need to survive yourself by swimming back to the surface. Each time you stop moving you lose one breath of air, but if you rise too fast aerobullosis, the diving sickness, takes you. You can't panic. Swim out, calmly, peacefully.

Game is done during Global Gamejam 2025

How to play:
Swim towards the surface with left, right and up arrow keys. Every time you release any of these buttons you spend one breath of air.
