Nice music selection to drive home the stranded environment! I was going crazy and refused to give up until I got the fragment on the left! Talk about a pixel perfect fit. If I had any suggestions it would be to have have more oxygen or have cactus pops reduce oxygen slower. As of right now cactus pops are an immediate game over rather than a risky rush back to base due to how fast oxygen depletes. All depends on what you're going for I suppose.
All in all fun game and great submission to the jam, cheers!
