Design: The design is alright, symmetrical which isnt always bad. It supports good cover and gives good allowance of movement for the player.
Gameplay: The gameplay has a fastpace, as long as you dont get campers hiding in the shadows behind their forts.
Looks: I like the custom textures that you used, it goes along with the lasertag theme. The only problem is that is very repetitive with the grids, maybe try adding a different flow to the textures so its all not the same. Its is also quite dark, maybe lighten it a little bit, but not too much, just so they can see each other from the other fort.
