Yeah. I've tried this a couple times, and I'm in the same place you are (as far as my opinion goes at least - I haven't even gotten as far as you have).
Die and respawn with only one health, in spite of having picked up a couple hearts. Need to get back to the teleporter to get health back - but can't use the teleporter to teleport. Restoring health doesn't matter anyway because the only places to go are either blocked by bats, or blocked by spikes. Can't jump over the spikes because the jump isn't possible except for those random times when the wall jump suddenly hits escape velocity. Can't jump through the spikes or the bats because damage is dealt continuously - so what's the point of extra health? Can't teleport back to the teleporter I activated after one set of lucky wall jumps, so what's the point of the teleporter? There's a bar of some sort at the top of the screen that starts off empty after death, and refills. It must be relevant in some way - what's the point of it?
Maybe the game description was being very self-aware in the claim "something went wrong."
