the lag is the wort part because I can't control that, but I do know that if you download the .sb3 file, and load it in turbowarp or forkphorus, it doesn't have much lag (well, it lags like crazy when sharing a level in forkphorus).
thanks i will have a super pc one day to upgrade my fps
It's not your pc. It's the website that is used to run the html file. yeah, it's not itch.io (I think, I haven't looked into it much).
