Oh my god I also felt the level design crunch at the end of the jam as well, so no worries there. With the softlock, the little orb guys stop spawning after a few resets, so there's no way to reset the room since the R key is broken and you can't force yourself to die. You're just left with 0 rockets after you've used all of them, with no way to get up to the last platform to kill the last guy.
