Short, but goddamn terrifying. Getting to the ending took decompiling the game in JPEXS and making a path for myself, so I could avoid noping out from fear.
"Blind" turned out to be the hardest one to get - it took a shocking degree of willpower to not hit F5 whenever that battery ran low.
I *did* end up finding that getting the final cursed object after running out of battery power led the "game over" audio to play during the ending. I don't blame you for not catching that.
