This game is surprisingly well made, from its dark eerie atmosphere to its music/soundtrack and the conveyance of the story with minimal dialogue allows the game to pace itself well enough. The gameplay aspect is also fascinating, with the mechanic of actually requiring you to die in order to solve puzzles since certain actions can only be done in certain forms.
I commend you for making an interesting entry to the jam. The package is cohesively well thought out and the cliffhanger definitely leaves you wanting more. Keep up the good work.
