One of the few games we tried out at PAX East this year that had any kind of mobile device mechanic tied to it was Alt-Frequencies from Accidental Queens. When we played this demo we did it sitting down with earbuds hooked up to a mobile device so we could play the game the way it's intended, which was a smart move that you don't see a lot of game developers do. Most of the time you see anything mobile chained to a desk or under constant surveillance. Here we were given a comfy chair and the ability to play, which if I could give awards to developers at conventions, I would have given AQ one for providing chairs after the BCEC floor killed everyone's feet.
This game has you listening to the same three minutes of audio in a time loop that no one realizes they're in except for you. You switch between radio stations that are all telling their own stories of the day in their morning shows, but all of them are connected somehow. It's up to you to switch between the stations and change what happens by essentially connecting the dots that link all of them together. When you gather all that info and redistribute it, you change what happens during the loop. Our guess, even though this was a demo, is to figure out how to get out of the loop altogether, which is an ingenious way of using audio and mobile tech together for a game. Alt-Frequencies is set to be released in May 2019 for iOS, Android, and Steam.
