Well made dark and spooky atmosphere- definitely a fun play through if you're a fan of horror visual novels. The idea of there not being enough oxygen to last helps seal the story together in a fun way.
I play your game in the video below (as well as a couple others) and left in depth feedback on the game. You can also vote for your game to advance in my channels tournament for best indie horror of february!

I'll be 3D printing a scene or monster from the winning game to give to the game dev.
