I can probably submit some examples tomorrow, but you can add slope jumps in a sequence so if you fail on one of them you have to restart all of them, and about what customcoaster said, I would avoid that because of how difficult it is for mobile players (like me) to do things like that in a game.
Twitching barriers
1 second jumps (the barriers deactivate in one second)
Fake barriers (no collision)
Invisible barriers
One block to one block 13 block distance between apart (it’s possible)
Like the one before but from slope to slope
CC! We haven’t seen you for a while! (On this site)
(Or at least I haven’t)
Tou can also make “fake” platforms. Just trun off the collision of the prop or barrier, and maybe make it a different color or tint for other duplicate props, just to hint the player that they will fall through if they jump on the platform. Hope this helps!
Credits to string. How about a glitch slope jump? Where the slope deactivates whenever the player lands on it. It would reactivate when the player jumps of it.
