Tried for the fourth time now, got super dizzy the fourth time too so may as well give a comment now. I like the idea a lot, the concept is great, haven't seen another rage game in this game so far, so good job. The game is unreasonably hard, and the furthest I've been to is the yellow P (?should be) on the left hand side at the brown zone. It's super punishing that once you fall, you directly go back to the start without any buffer. Not complaining too much about that, though.
My main complaint is the game really needs some sort of tolerance on the raycasts, as most people don't really have 360 no scope aims with their mouse. A bit of leeway would be well appreciated, especially when you've gained a bunch of speed to launch yourself up. Another issue is that the collision of the alphabet magnets really screw up the movement and momentum, and the bump is also what worsens the whole motion sickness thing. Consider not letting them affect the player. Also, for the sake of those who need a seasick pill right now, please add in a FoV slider. FoV change is one of the many things that can help reduce motion sickness in games. This is especially important for a fast 3D game like yours.
Anyway, this is a solid entry! Well done. If nothing else, I need to lie down for a bit and wait it out.
