Oxygen Harvest is a puzzle game about flipping tiles to generate oxygen!

My first Ludum Dare game went better than expected! But I was still panicking up until the last few minutes. My time management skills could be better...
As soon as I saw the theme "Harvest" I wanted to create something non-violent, and for some reason space-themed. The game has roguelite-style passive upgrades in it, which I unfortunately didn't get time to balance, so the game is a little on the easy side. I'd love some feedback, because I'd love to continue working on this after the jam ends.
ps. if you play the itch.io link, you might experience some audio pops occasionally -- I'm unsure why this is, but it's happened in previous Godot uploads before despite the audio pops not being present in other builds of the game.
