The time is identical to the submission because of frame rules. Only the screen in which the mistake happens and the final boss are different, because of RNG.
Finished stage 1 on which I spent most of the time figuring out what 'dance moves' to do in the elevator area ... also I've tested out whether the NEWT suit would be useful in later stages and it isn't ... furthermore I had to carefully choose which enemies to kill and in what order so that I won't lose time while moving and to get 3 valuable items in the elevator section ... enjoy :)
