Hey, idk if your gonna hear this but if you ever want to try reaching A-1000 here's some tips from my experience with A-900: 1- never take any suspitions of A-60 lightly, allways hide if you think he's gonna spawn 2- the 5th A-60'(in A-60' sequences)will allways ambush you because the flashlight stops flikering for longer than normal and that might trick you into thinking your safe 3- A-90 almost allways spawn wend A-60 spawns/despawns (he also does that to A-200 for some reason), same goes to A-250 but only wend A-60 spawns 4- A-120 and A-200 can be avoided in the same way because A-200 is around the same speed has A-120 in A-900 5- pride is a good charm to use because it gives more answers to A-60, who will be your biggest threat because of its massive speed and constant spawns in A-900(seriously you can't make it 6 rooms in A-900 without A-60 spawning) 6- allways keep yourself calm, even in new A-900 milestones, otherwise you will start to mess up! a good way to avoid this is to not pay attention to the room number 7- you might know this already, but A-250 will only attack wend there's no other entities, so if A-60 stops spawning and A-250 is still constantly shaking the room but not attacking, that means A-120 (or an A-60') probably spawned
