The level design is disappointing, the first levels are too linear and when mixed with the small amount of enemies that this game has, gets boring fast. The last levels have so much non sense puzzles that is impossible to not get frustrated. The mid game is solid though.
The art direction is very interesting and provides a new horror look compared to the previous DOOMs, although the enemies visuals doesn't look right with that desaturated reddish color.
The soundtrack works as an good ambience sound, but looks very similar to each other. Besides, it doesn't seems to suit the (not very fast, but still) fast paced gameplay. Often the music just stops and I had to finish the level with complete silence.
And the saddest thing, the lack of proper animations on the guns, almost every gun in the game stays practically motionless when shot.
