A couple things:
Why is the game in black and white? I think it would look really cool if the art was more analogous to the promo art.
The camera honestly makes me sick, I couldn't play really long. I'm sorry.
The constantly jumping is a unique concept in these frustration ascent games, but I don't think the camera should move like it does.
Keep going
I made it mostly greyscale since it's faster to make stuff for and making certain things red to it as an enemy projectile, mainly to make it really simple to spot what things are. Originally there was fixed camera positions, but people didn't like it due to having to switch them when jumping to where new cameras are, which is why I changed it to what it is right now. Maybe I could make the camera position only change when the player is on the ground instead of it being constant, but I've been trying a lot of things to make the camera work well overall with allowing visibility and I haven't figured out the best implementation overall yet.
