Now that was a little cute game!
I really liked the art style and the beginning cutscene. The Concept is great but the ocean playground is a little empty if I could put it that way. Maybe you can add some background animals and put the air pockets closer to each other and let them give Bailey more air so we can progress even further
A little bug that needs to be addressed - when I swim up I can constantly go up and down and refill my air timer in that way I can make Bailey last a couple of minutes underwater. The same thing goes for air pockets.
Cheers!
