You can but you can't use it for any% because in the cracked version you get everything unlocked at level 1

You have nitrous on lvl 1 if you apply the Ultimate Unlocker Crack from the Resources tab, I don't know why the crack makes you have everything from level 1 no matter what you do but eh

Does it make a difference if you play the game on 30 fps or 60, 60+ fps, and will that run be accepted if you play on 60,60+ fps ?
