Treasurebot - Gem Collector by Jerm
You are Treasurebot. A drone built for the purpose of collecting gems from the mysterious Gem Cave.
Unfortunately, due to a software glitch Treasurebot can only collect gems in a particular order. So be careful not to pick up the wrong one!
Journey deep into Gem Cave and collect as many gems as you can.
Note: the sound effects are probably a bit too loud, oops. You might want to turn your volume down a bit before playing.

Update (2021-4-30): I've made a post-compo version with quieter sound effects and added a new sound effect when you collect a full set of the same colour gems. Link is below.

Did you code the levels with noise or did you draw them manually? They don't seem procedurally generated. Interesting!
