Ouch, I should have tried harder to find playtesters for the latter half of the dev cycle (I had none)
Protip for everyone to save yourself some unecessary headache: it walks faster than the player and charges at you if it and the player is lined up on the X or Y axis. It has difficulty catching up to you if you make sure you're not aligned vertically or horizontally. If it makes a grunt noise, that is a cue to make a 90 degree turn to avoid its charge.
The exit on that first map is to the South West.
The second map is just a looping map and you automatically exit after roughly 20 seconds more or less. The timer goes faster if the Lost is bumping into obstacles or if your health is low
