Quick review :
Map itself : The starting platform should be moved to the center of the plot considering your map is 120+ wide which will result in a //cut
Also consider lowering the starting platform down 10 blocks maybe to not cause trouble with the "30 blocks down from spawn causes you to get tp'd back up" (ask mods if this wasnt clear).
Build : Looks good on the outside, everything else is way too detailed, there's just too much going on it hurts my eyes, also most of the map uses a very dark palette, which makes everything harder to see and a pain to figure out. Basically you overused heads and panes as decoration and it just wasn't needed (also too many heads cause massive frame drops).
Parkour : Oh my
- 1st slime is hella annoying just get rid of it and its barriers
- You used x facing piston heads, which are banned because they don't behave properly
- Checkpoints are a mess, they should be spread evenly-ish at least
- Overall your map is a "hard jump fest", which wouldnt be a problem if the jumps were "only hard", not on the level of final rankup server parkour map.
- It just never stops, "you just did an insane butterfly neo with a weird setup ? Nice take this 3b stairs momentum triple neo then go ahead and do a double 45 strafe ontop a landmine". An insane map contains around 120 jumps yeah, but not all of them are bwmm or cross neups, consider adding more of transition jumps.
- I didn't bother doing half of the hard jumps in creative mode, why would I in survival.
I actually wonder what hardcore parkour players find fun in repeating a single jump 342 times only to find a setup that takes 10seconds to properly set up every time only to fail said jump because you jumped 1 tick too late.
Oh and also I couldnt find the ending after 5minutes of flying around the crater.
