writing as an absolute beginner tier player for these games + with the feedback i've written last time in mind, i can safely say the difficulty curve is much better and that i feel like all my previous feedback was addressed. there is adequate space between sections where I don't accidentally yeet myself backwards, and the challenges are easily readable. I know exactly what I need to do after a few seconds, it's just a matter of doing it.
here are some miscellaneous suggestions/ideas, but I think the game is in a good spot and that you're clearly moving in the correct direction
-I don't like that the first checkpoint isn't reached automatically, but instead is a bit out of the way. I think games where you naturally pass by the checkpoint do this better, since when presented with the option of a) do this jump to reach the checkpoint or b) proceed without it, everyone will want to do (A) first unless they're doing some no-checkpoint-challenge run. It depends on your intentions, but unless there is a reason as to why the checkpoint isn't in the path to the next challenge, I think it should be moved there.
-I'd expand on the eye mechanics by making the blood or whatever it is splatter be more prominent. The issue with limited vision is that you don't know where you're going, but if the path is outlined by a ton of blood, you still have a chance to proceed. I'd say double down on the idea and make the impact/death blood splatter 4 times bigger, so that you can tell the outlines of the playable area even when blind
-right click to change color is weird. I think it's a very important key being assigned to something not very important. the only way i can see this being used often is if you're playing this on one computer with friends, and you swap colors between runs to show "who dies where". I think you can do this by binding it to the C key or something, since I'd accidentally press right-click and pull up the menu, which covers the entire screen and I'd panic and so on. The concept itself is fine, I'd just rebind it
I am happy with everything else. Perhaps the difficulty is still a tad bit too high, but I don't want to comment on that since I'm clearly out of my element and wouldn't be able to say what the correct difficulty should be like
