Try To Add Flipping Platform in You’re Obby, if I’m making a Obby i would add it,
basicly every 2 second the Platform Will Flip 360 Degree and player would need to jump at perfect time (add a jump boost to players)
idk if you like it or not tho, it’s just my Idea made it like in 2 seconds
but if you do like it, Pls Credit me! :DD
Try do a conveyor on a stage where you can’t stop moving quickly and you must jump over some parts that are on the conveyor that will kill you if you step on them.
I have this older obby with several stages that has different and cool concepts. I recommend checking it out - as I’m positive you’d be able to get some ideas from there.
