Pls jump - game

So,after like some months I’ve decided to get back on working to my first game ,named BloxPeak first and then changed it to PLS JUMP.
I’ve abandonded this project because the main system was freezing the game of the user for 1-2 seconds and because it was slow .
BUT after months , I’ve decided to remake the main system code,so now it will not kinda freeze the user game and it will not be slower and slower as the tower is changing on the game(every round the game got slower )
So,now the game kinda works , i mean maybe i will need some reviews? idk
