I tried the game once again and this is a fantastic update, I really like everything. Animations, levels, hard mode... Teleporter is also a nice idea since the levels are big.
My only major complaint is about sound:
1) Hailey has become very talkative now, after every action she moans or produces some sort of sound, can't figure if this was also a problem before but I really noticed it now. I think something that would help a bit is if she could have more random sounds to make it less repetitive. The sound I have in mind is the one when climbing on a rope (hurt2.wav). which in certain levels you hear ten times per minute.
2) Some animations are missing sound: the "swoosh" pickaxe sound when attacking from rope or proned, some enemies do not make noise (eg. 2x spiders) and in general the voice seems too loud compared to effects (would appreciate a slider to reduce the moan volume).
3) I modded your game with DnSpy so that every time that she would normally moan I now make her moan only with 1/2 chance (random() < 0.5). You should try it, it makes the sounds less repetitive.
