Well, the game was hard as nail but overall the atmosphere you've set up was top notch. With very few elements you've managed to build some interesting gameplay tension and I found that the main mechanic while being simple as a bar to fill up was geniously used and served well the purpose. I loved the SCP like vibes that you've created, and the classified document writing was well made.
Unfortunately i couldn't finish the game even after few try, it seemed impossible to get to the ending without getting killed too early.
I see a lot of potential in this game because it evoques fear with simple and soft elements, well done Grim !
