Wonderful game! I thoroughly enjoyed the story (and haunting 'Ethan')! The whole phantasm mechanic was a fun little treat! It's a really cool way to give more details beyond what our observation provides! And that one part about Ethan's sister? Not even knowing her little brother is dead? Pain. Truly.
I had a lot of fun piecing every clue together! The preview of the IDs on the game page... Ohoho! What a fun foreshadowing! All in all, great work! Beautiful art too!
