I like the aesthetic and old school fps gameplay.
I think most of the difficulty comes from the (in my opinion) rough readability. As in, it's hard to tell what is actually happening and what you need to do in order to overcome the negative things happening to you. Even after getting a little more used to it I still had trouble keeping track of things.
There were also times where it felt like my number 1 ability was not clearing out the error 404s.
Another suggestion I have would be to change the pause button to be more accessible to the hand on the WASD keys, since there is utility to pausing and taking time to move away from the mouse or movement keys doesn't feel very conducive to the gameplay.
This was still a cool concept and was well executed in the time we had. Well done!
