the game is alright, a little too short and the boss wasn't really a challenge... I have to say  good job on making the game in unreal as I know from experience it can be quite challenging! Good Job

overall a good game, but quite lacking in a few departments, other than its too short the boss fight was a bit weird and the boss wasn't really smart or posed an interesting challenge, but the idea is quite nice and the execution was very solid, overall good job.

The game is scary but way to short! and also the theme is not respect. I had fun though.

Despite the name, there was no real boss battle,  It did looked nice, but I experience lots of visual Glitches, also the culling of the walls was acting weird, The "Boss" is super dumb and it doesn't really do much. 

If it was a real challenge, the Idea of gathering things to defeat the boss would be a good one, Remove the pistol and imagine that instead of gathering keys, you gather parts of a gun or parts of a bomb, and you need to escape the bosses attack while you do so, after that you need to find time to build that gun and attack the boss.

PD: I like to think that this is not an FPS but a 3rd person shooter in which the playable character is a giant pistol
