Horror comes in many flavors... just don't tell that to whoever's filming the seventh Paranormal Activity movie on some Hollywood lot right now. Case in point: Steam's horror section is a cavalcade of creepiness, with games like the Five Nights at Freddy's franchise sitting alongside Amnesia and The Evil Within. And lest you think it's only possible to scare in three dimensions, there's also DISTRAINT, an indie 2D side-scroller that's dripping with horror themes. The game popped up on Steam last year, but now it's available in the Play Store for free.
DISTRAINT tells the story of a pixelated property pilferer named Price. After seizing an old woman's home via some shady means, Price (whose name will almost certainly prove to be ironic) tries to get in good with a business partner. Odds seem pretty good that he'll have to pay for his hubris at some point - the nearly-black environments scattered with stylized points of light from fixtures are a bit of a heavy hint. While players are given direct control of Price, this isn't an action game - progression comes through exploring the apartment complex, collecting inventory, and solving some basic puzzles, a la point-and-click adventures.
The game is compatible with phones and tablets, but it's clear that a lot of work has gone into the graphics and gloomy atmosphere, so play it on a bigger device if you can. (Sadly, it's not available for Android TV.) Note that the game is rated Mature, and its heavy violence and language aren't suitable for kids. A single $1.49 in-app purchase removes advertising, which seems more than fair.
