I’m a sucker for games that follow the design of Wolf3D. This does have a few of map nitpicks that I think relate to readability, since you need to rely on reading the layout of the room instead of what the room looks like. I could see this having a larger variety of ceilings, walls, and floors. On top of that, maybe tint the windows a bit.
Oh and Mousegun’s real fuckin’ cute. 10/10 – Collyn
