Congratulations on the run!
speed runs started all the way back at full arcade machines, as a way to track high scores for old racing games and it slowly blead into other genres of games -- so the first one was probably Gran Trak 10,Taito’s Speed Race or another racing game from around 1974
Hi fish! as of right now there isnt a standard for splits for any% fullmoon, but there seem to be 2 main ways- Act 1 Act 2 Act 3 or the way i personally like Chapter 1 Chapter 2 Chapter 3 Boss feel free to do what you like for splits as far as ive seen so far no ones timing segments of runs so you should be good with whatever. i start the run on the click of start on the class screen, and so do most it seems. for recording i use livesplit to track time and OBS to recorded i find both work very well. I hope this helps! come join the discord if you feel like it, peeps can help more there too
