Beglitched [official site] may be the most adorable hacking game I've seen. So long, scrolling green glyphs! Please stay in the '90s with pleather trenchcoats. (Aside: oh no, when will the '90s revival reach The Matrix? Or maybe the fashion it inspired will become more palatable with modern restyling. Anyway!) It's an upcoming puzzle-battle game about hacking the planet as apprentice to the Glitch Witch, probing networks and battling hackers on your cutsey pink deck.
Developers Alec Thomson and Jenny Jiao Hsia call Beglitched "a puzzle-battle game with an emphasis on exploring networks, both physical and metaphorical" with "a combination of roguelike, match-3, and deduction mechanics". As you poke around the cyberweb in what look like roguelikelike webs, you might find yourself being hacked, which launches into grid-based battling where you need to find the hacker and cut them off. I wish I could tell you more about how it works, because what I understand looks grand.
Beglitched is trying to crack Steam Greenlight right now. It's lined up for release in "early 2016" on Windows, Mac, and, obviously, the leet hacker's choice - Linux.
