The graphics really seem off to me, but I guess it can get scary

I think the controls here can get confusing since they do not have directional keys and you just need to press one button and hover the camera to navigate.

It's a first for me, and it's not the usual controls for a first-person zombie shooting game.

But I would say, despite the graphics of the game being at the lower end, they compensated for the feel and environment of the game, which makes it decent for a paid game.
