Well, i want to give you a hand so i'll tell you all thing you could fix (at least things i noticed about)
https://prnt.sc/ts5jvu overlapped wall throws u down by walljumping there/jumping there sometimes even with 60 fps
https://prnt.sc/ts5da5 make that wall i marked 2Px/3Px less large to the left and same for the other side, so it makes the movement feel way more smooth on bottom
https://prnt.sc/ts5def same here but just 1 Px to the right and same in the other side since its symmetrical
https://prnt.sc/ts5dk9 make the region that detects the caracter to open the door bigger, so this doesnt happens
https://prnt.sc/ts5e76 you could add invisible doors there or just make a whole platform besides just those 4 on those places, needle will have enough penetration so you can give functionality to the weapon there
https://prnt.sc/ts5epb Also this, so people doesnt get stuck for any reason there
https://prnt.sc/ts5fbq be careful with overlapping, i know it looks better like that but im sure you dont want to jump there for any reasons and do a weird jump there
https://prnt.sc/ts5fq3 i will be honest, i didnt even notice there was water, you could add the same amount of water there so it looks darker and more visible
https://prnt.sc/ts5g49 those lasers doesnt look good there
https://prnt.sc/ts5glk Slowing movement here was on purpose? if it wasnt u could make this area bigger
https://prnt.sc/ts5hxs cut the area i marked there so it doesnt slow the movement thanks to the head of the character
https://prnt.sc/ts5ioz put an invisible wall there, so ppl doesnt get stuck there for any reasons (nades, glitching)
Well thats all i found in around 5 minutes, i wish you the best luck
