idk if you can because if i cant. idk what im gonna do.

It is not allowed to speedrun this game on Everest. You can just hold right on the titlescreen or use the Olympus launcher to launch into the vanilla version of the game. So it shouldn't be a big hassle to do runs on a vanilla version

do i still need to hold rigth even when opening in steam?

yes, steam opens everest by default

ok thank you

For me, it was a bit tricky as, on the vanilla version, you have only 3 saves and my 3 first saves were already taken. So, I had to move a save to do my run.

I reccomend keeping the third save slot empty.
