What a really fun game!! Great work!! The audio when collecting energy/orbs is really nice and suits the background audio really well. Controls are simple but the diving to then gain height afterwards is a great mechanic. I love the way your 'levels' progress, it's done very smoothly and makes sense in the world you've created!
Kept getting pushed back down once I got to the new enemy type area - they're tough but avoidable if timed correctly so seems very balanced! After playing for a bit I did notice the orbs sort of blending in with the rain but that's my only feedback!
Well done!
