I found it a bit hard to play for too long, as most of it is me blindly moving along a labyrinth. The gameplay was just moving from air pocket to place to back to air pocket, which I also find not too good, for the reason that if you have a certain amount of time to spend in between in between these places, it will either be designed for me to make it, or fail. This could be fixed with obstacles, but is still not the best of mechanics.
Art on the itch page as well as thumbnail are great but lacking in the game. using shapes and colors is fine, but right now the design language was a bit scattered. Having a white area for oxygen, and then having a white hexagon (also an area) for something else and not being able to use it for oxygen is confusing.
I also understand that you had a deeper meaning behind the game which is great, but I unfortunately never got to the part where the meaning became important in the game itself.
