''Set all 999999999'' (nine digits of 9) for the fastest gameplay. But ''set flight 100'' ''set jump 25'' ''set movespeed 40'' for playable game, otherwise it will be unbearably fast.
you forgot to teleport to 0 0 0 (it instantly teleports you to spawn)also you can set all stats to 50 for even better stats then normal and if you really wanna make it obvious your using debug set god one and make yourself invincible
