So, who's playing this, then? Exapunks, the latest from mind-bending puzzle maestro Zachtronics, which builds on the previous programming games - TIS-100, Shenzhen-IO - and wraps it in a tasty layer of 90s-era cyberpunk aesthetic. It's bloody marvellous, and responsible for no small amount of missed sleep over the weekend. Trouble is, only a couple of people on my Steam friends list play it, and part of the fun is trying to out-optimise your friends - so if you're playing it, shout up and we can add each other! At the moment, though, I've hit kind of a brick wall on one of the projects - but I'm hoping I'll have an epiphany soon enough.
