how this minigame will work: I'm thinking that if you get in a locker, then there is a rare chance it is a "fungus locker" filled with spores, the vent will spudder with said spores and you have to hold the space bar to breathe but if you breathe the spores in any frame, it gets harder. aka the spores come more often and if you lose you are given the status effect "fungal" for the rest of the game, where 5 hp will be lost every minute, giving 20 minutes over all to get to door 100, where all status effects are removed. you can leave the locker at any moment, but you will not be able to move for 3-5 seconds due to lack of oxygen. so in some cases it would be better to do the minigame instead
how it looks: there is a bar on the left of the screen, its your oxygen level. hold space to increase it. if spores are about to appear, dont hold space or you will breathe spores in and activate the next level. at level 3 you have to be near frame perfect to successfully gain to your oxygen bar. if you leave the locker during level 2, you will be frozen for 3 seconds. during the transition, 4 seconds. and at stage 3, you will be frozen for 5 seconds. though. in rare cases, you could get a jammed locker that will have the same minigame but also require you to mash a different key every 3 seconds. otherwise, if you fail the minigame, you die. (the lockers have vents inside them from behind so people inside can properly breathe, and the fungus comes from SOMETHING outside. where. or what it comes from? that's for you to imagine until further notice)
