Visually impressive and the idea is great. I wasn't sure what to do to solve the puzzle tho and just kept guessing wrong. Maybe some hints?
Keep jamming!

Thanks for playing and the feedback! The puzzle details follow:
SPOILER
-Each key opens a certain number of portals.-Keys are more likely to open red portals than blue portals.
-One key opens all the portals; only this key opens the center portal.
-Key location, key appearance, and portal location are randomized every time a room is entered.
-Upon entering, opened portals with blue glyphs add 25%, 50%, or 75% more air up to the maximum supply.
-The center portal refills the air to the maximum.
-Upon entering, red portals take 25%, 50%, or 75% of the remaining air supply.
-Pass through any seven portals with air remaining and you succeed in leaving the prison.
