Hopefully this is the last update!
I added a second hit box for the barriers, and added a better explanation of the forward jump, plus a hint near the top (right before you have a chance to fall waaaay back down) that indicates the player should be looking for shortcuts.
I decided against the indicator for when your jumps are used up, I didn't like the look of it and decided the system was simple enough to grasp not to need it. (and by extension I also am not turning the jumps off when you fall through barriers.)
I fixed that edge case with the camera zoom, Another zoom out level would require more redesigns than I am willing to do at this point. (and there shouldn't be edge cases like that anyway, I want the player to be able to see their next jump at all times)
And the big one, the difficulty curve.
Instead of adding easier parts, I decided to go the opposite direction and ratchet up the difficulty in the first half. I made it much easier to fall back to bottom, so now the tension should rise appropriately the further you climb. Whereas before the tension was more of a straight line, now it should spike at each interval. I also made the very last stretch as hard as i possibly could, while keeping the layout the same, now the jumps required of you at the end are very precise and use your entire move-set.
p.s. I don't expect you to play-test again, I just thought you would appreciate an update.
