Retro aesthetic suits this eldritch featuring shooter, fact that humans are the enemy is fairly fitting, pacing, playstyle and even secrets are all quite appretiable, some enemies give challange but thats always fair enough as long as it si predictable and plyer dosent say run around with their sword like moron for no real reason... arhrem spoilers .P
Retro graphics are bit of an anachronism because that complexity of levels would not have been possible in the 90s, tho dose once again compliment the whole here - as story goes awakened to the unkown time holding ancient knowlidge and values.
Setup (armor removal) first is kinda awkward mechanick but managible, game dose feature key re-bindability to help with expedient adjustement to situation.
