Honeyslug just released Poto & Cabenga, their browser-based one-switch game that was made for the Gamma IV party (and was chosen to be displayed there). You control both Poto and Cabenga with one button, and the way it’s done is pretty nifty… definitely a bit of a mind-bender at first, though. I like the art style!
