Divide By Sheep is a fantastic math-based puzzle game, focusing on problem solving in mathy ways rather than number drills. It's bright and colorful, but with a dark underbelly: fling sheep through a wall of lasers and you'll end up with twice as many half-sheep, complete with blood splatters and exposed (but clean) bone cross sections.
I previewed it in May and don't really have much to add to that. The PC (Windows and Mac) version is pretty much identical to the iOS version, but the mobile-friendly interface works just as well on the PC as it does on touchscreen devices. It doesn't feel like a crappy port; both versions are of equally good quality.
I was really hoping they'd go the extra mile to help parents who wanted to let their kids play this wonderful mathy game but didn't want blood splatters ensure that kids couldn't turn the gore back on, but they have not. The press release came with a fairly long story about how the game became the adorable but dark experience that it is, though, and after reading it I think that perhaps my hopes were in vain from the get-go. It's an interesting story, written by Alex Nichiporchik of tinyBuild Games and posted in full after the break.
The game is available on the Apple app store as a universal app and comes out on Steam later today.
