Thank you to everyone for the useful feedback!
I agree that it should be more obvious when the player is hit, I'll add a sound when I develop it further, somehow that never occurred to me during the jam. I might also make the screen flash as well but there's already a lot going on visually so I'd want to be careful with adding more visual cues.
I'm not sure how to make the hitboxes more obvious while keeping the glowing look of the orbs, I've been a little lenient with them for that reason so hopefully there should be more cases where you thought you should have lost a life but didn't than cases where you thought you shouldn't have lost a life but did.
The motion sickness seems to affect some people more than others. I think adding a decreased motion option where the conveyors don't move forwards and only point in the direction they are pushing would be a good idea, I'll have to get some other people to test that if I implement it since it doesn't affect me personally.
A curl noise field would be interesting! I haven't seen that before. Sadly it wouldn't work with the way I'm doing the conveyors at the moment. It could be an interesting opportunity to learn some new things further down the road, but I doubt I'll get the time to look at that any time soon.
A few people have mentioned that they really like the music and I would like to clarify that I did not make the music in this game - The song is Straw Fields by Rolemusic which is licenced under a Creative Commons BY license and is available here: https://www.freemusicarchive.org/music/Rolemusic/Straw_Fields/03_rolemusic_-_straw_fields. I'm glad I picked a good song though :). I put credits in the bottom right corner of the menu screen, but maybe I should make it a bit more obvious with how much the music adds to the game.
