Speedrun viable. Fun facts about Verum Rex: If you 'Retry' during VR, the RNG changes and the purple ring doesn't kill the central enemies until ~16"00. If you 'Exit' and 'Begin the Game', the RNG present in Any% speedruns will always be present, with the ring killing the central enemies as early as ~14"50. Also had a unique pattern where the ring didn't spawn until 25"00 into VR, was idle in the Verum Rex - Beat of Lead - screen for ~5 mins. Another small bit, when you config the camera sensitivity as Sora it doesn't transfer to Verum Rex. So there is no way (That I don't know of) to increase your camera turning speed.
