I am gonna say this, this games is SO GOOD, I honestly wasn't expecting much because saying you took inspiration from the works of Junji Ito is setting the bar a little too high but GOOD LORD you jumped that bar and the next two. The intro animation of the door was great!
This is true horror content, no cheap screamers just PERFECT scary environments full of tension and a ongoing mystery plaguing every inch of your brain as you play, Masterful use of the sound and the darkness to play with our minds. That monster will haunt my dreams tonight.
Honestly my only suggestions would be adding more choices if possible but that's just personal taste and maybe adding a little more expressions to the character portraits; Can't wait to open the other 2 doors!
Once again, great game!
