This is a really cool concept! A very solid take on the "blind as a bat" cliché that really taps in to my constant desire to play Flappy Bird style games. There is a surprising depth to it - you start to realise details like how the fireflies(?) act as signals to where you should be going/which way the camera would be bending.
My only gripe, like others, is that collisions often felt far too punishing, and it wasn't too clearly communicated why you were colliding with things that, from the player's perspective, seemed like they should have been further away.
Outside of that, a fantastically original take and a solid game overall. I managed to get to 79%!

Thanks! Wow 79%, that's impressive! I'm glad you noticed the fireflies (I actually just meant them to be regular flies but because they were buzzing they'd be giving off noise which would make them light up, but when I designed their movement I found they did remind me of fireflies), their purpose is exactly that - to show the player where the camera was going to be going. And yes, I agree about the collision issue - the player's collision box definitely should have been smaller, and as for the depth perception - that I haven't figured out yet with the echo location shader.
