Blue is not bad, but I think it's not equal to other colors, like there's not enough blue things to justify it with only the orb and small echo location waves.
I was just ideaguying on this, I think I'll move echolocation to be a skill icon and the blue orb will become a yellow orb and represent stamina. I'm thinking about making flapping more powerful but limited by stamina. As you found out, you need to use the flapping to help you turn, so I want to make it more available to players if they've saved their stamina.
From an overall color perspective, yellow may clash as well. My thought was make the game black and white with hints of color, but having a large yellow UI element may be too distracting. Perhaps yellow FX around the flapping or something.
There's a clamp on looking down, but not on looking up - you can do a glitchy flip.
This is intentional, hopefully the downward clamp doesn't feel too restrictive. Flips are a little odd, I may need to find a way to make them complete smoother. Other aerial maneuvers like Immelmanns I'd like to add or make happen more naturally.
Are waves different or it repeating?
It's just repeating, only your health drains faster and faster. The wave based gameplay was put in to test the mechanics, I'm going to ditch it once I make a bigger map.
Thanks for playing!
