Slam City Oracles[ official site] is a free slam 'em up with a riot grrrl tinge from the powerful programming paws of Jane Friedhoff and artist supreme Jenny Jiao Hsia. The premise is simple: You and a buddy continuously slam into the ground below you and cause as much damage as possible in a two minute timeframe. But O it makes my heart go pitter pat with teenage nostalgia, opening up those 90s Bikini Kill valves and pumping out nutritious My So Called Life vibes. This is basically Super Smash Brothers for the teenage girl experience.
Here, have a look:
The game is out on Itch for Mac, Windows and Linux - It's free, although there's an alternate Pay What You Think Is Fair option too for those of you feeling particularly patronly. Oh, and it's got a hell of a soundtrack from the wonderful Brooklyn-based band Scully.
