Appreciate your feedback, you can easily outrun the nun as you move much faster and there are plenty of places to hide, the riddle note you mentioned is also not needed for any puzzle while the nun is active, as she first spawns after the projector puzzle and begins actively hunting the player. I understand it takes a little patience but it is def doable in one run and the game was intended to be played in a single playthrough. Furthermore the nun cant actually kill you in the second level, so she is only a threat in the first and since the game isn't super long i didn't add checkpoint plus it could kind of dull the whole threat of her if you simply can die with no consequence, and to get back to her is easy enough once you've done the puzzles once and know the solutions. Thanks!
Thanks and if the game was longer I would for sure add auto save as I usually do this for longer titles. Glad you enjoyed the game otherwise! If it helps, after she spawns you only need to take the 4 digit code from the projector puzzle, use that in another classroom on a box, get a key to the room full of books grab the ID card there and go to the elevator. Thanks I will soon be releasing a sequel to Mortician Final Night so def be on the lookout for that if you're interested! Cheers
