Yeah the boss is literally completely random with it's firing pattern, it just speeds up as you damage it (i didn't have enough time to make real attacks and such), I really should've made the elevator button more obvious but by the time I realized it was too out of the way I couldn't fix it other than quickly putting a yellow rectangle on it. I think the invisible enemies were hiding because you were pointing the light at them through the wall, and when you looked away they unvanished and jumped you, but I dunno since this didn't come up in playtesting. Otherwise, I'm glad you enjoyed it! <3
