Great game. Something different in every room to click on or see so no hold up in the pace of the story.


Well done!.I liked it,the game was made really well and tried to scare me well.Not gonna lie it was pretty good,didnt get all 7 of the secrets but got 6.Good job!

Nice game! Really liked it a lot. Played on my channel :)

For some reason when I started the game, all it showed was a black screen. (the dialogue was there though)

This game and The Apartment seem connected somehow

(1 edit)

this game was crazy lol, pretty dope ngl. that fire extinguisher was lowkey misleading tho, thought it was the way to get the good ending but it wasn't🗿 this game could definitely use some music tho, cause most the music in the video was edited in

love your game lots :):):)

hi, big thx for the great game. i love it. crazy. greetings from rosti 🙏🥰

Love the way the story was brought to life and trying to gather the different secrets was fun! Leaves enough questions to increase the intrigue. Here's my playthrough

Hi! Would you guys be interested in a Spanish translation for this or any of your other games? If so, please contact me!

i liked the game, it gave that mystery creepiness and the atomsphere was great, i didn't quite understand the story but it seems interesting , overall cool short game, :D

Enjoyed playing the game! Liked the atmosphere and horror elements! I'll be checking out your other games as well. Keep up the good work!

Can anyone help me understand this game? lmao

Wish I could have used the extinguisher, though I suppose it reflects on the player character's past ;)
