Really enjoyed the mood, the jumping puzzles and escape sequences. I've almost given up at one point, but managed to get to the end after investing almost 2 hours on my gameplay. Luckily I encountered only small bugs that weren't game breaking.
At the very end, where I needed the last fourth shrine. I even got it once, but I died before saving and I was confused if that was really the "thing" that I needed to collect. The game doesn't explain that you loose the item after you die. Don't get me wrong - it does makes perfect sense, but I just kinda forgot about it ^^"
Because of it, I traversed the map few times and managed to get the "Notes" item with binary code, which made me super proud :D
