Very cool game, though my browser seems to keep crashing while playing it—I keep getting "This webpage was reloaded because it was using significant memory". However, I was able to find the first two relics and I enjoyed the enemies and aesthetic that ya'll have got going on here.
I found the platforming to be pretty tricky here, and I kept running into the damaging sand walls accidentally when leaving a platform. I missed some jumps due to having what felt like not enough air control for the kind of platforming I needed to do.
Thanks for making and sharing your game!
