Great little homebrew game. Excellent art, nice suspenseful atmosphere with the minimal style and music.
I wish the English translation was a bit better. I would love to help if I could.
Yeah, I was excited because we can earn achievements for your game there! It's not an official site but it is slowly getting more attention and it adds an extra bonus for playing your game! I have asked for Cairn and Prima Materia to be added as well so they are also there, but someone will need to develop achievements for them.
