if i speedrun all chapter and i died in one map i reset in that map i died or i reset the whole run or other

you just replay the map you died in

If you die, I think you need to play the same map again.

i thought this was an existential question but then i realized it was about all chapter

yea so for example if you die in gallery you have to escape gallery since you died in it so your replay the map you died in
