Any plans to release the full game on Itch.io?


Yes, of course, once it's released next year.

Great! Looking forward to it!

Looks like an unreleased 32X game

This game is a lot of fun, Sit back take some octoblood and enjoy.

Thanks for playing!


Hauntingly beautiful, Yet playing it makes my Sanity crumble down slowly...

There are some elements in this game that I enjoy like the retro part and the spooky of the game. But sometimes there are disgusting actions from Kaf that make me kinda worried. Hahahaha. Good job Dev. Here is my 5 minutes+ Gameplay. Enjoy~

hey love this game so far may I ask how we make it full screen? maybe its thr format of my laptop but ts not letting me play full screen. for MAC.

Access the settings menu (pause with esc or from the bunker menu) and then change to Fullscreen mode under the presentation section.

Alternatively, alt+enter should do the trick (alt is called options or ⌥ on Mac.)

If you tried both and it doesn't work then fo you think you can send me the data files?  The ones for Mac are mentioned in the first post


top tier pixel art, does need a save though, i had to go to bed and was not gonna replay an hour lol

Demo NO Commentary
