can I continue speedrun if the game crashes? after vjan 1 when the location goes to vjan2 I have an unavoidable crash. (sometimes when a lot reloud the game is also crash, I can throw an error if necessary)

yes you can continue the run if the game crashes, and I strongly recommend using the "speedacademy" patch made my sphere as it prevents memory leaks (crashing from saving/loading to much) aswell as other crashes.

Also if you're speedrunning this game, I suggest you join the discord server for this game. as you can get help way faster. permanent invite link to the discord is on the left

If you're using the autosplitter it should also automatically pause the timer when the game crashes since you're no longer in a level, so the only time lost will be due to progress rolling back to most recent save.
