Citadel 1986 is unremarkable at first glance and shines the more you experience it. While playing through many zones I had a visible smile on my face, wading through water for the next key, not wanting to put it down, and being positively reinforced after a death with a quick restart. But only the most dedicated of retro enthusiasts will get anything out of it compared to some of the more inspired work being released on mobile devices today.
