This Game Monopolizes My Time
One of the most addictive games I've ever played. Most people's computers seem to run it imperfectly. It's mostly fine on my 2010 MacBook Pro, but almost all the pieces are origami-like shapes, and can occasionally glitch into even stranger shapes. Also, the dice are featureless cubes, so I never get to see how I get the numbers I roll. I also wish there were an Extra Hard setting, as even Hard often leaves me craving more challenge. But god, on the whole it's just wonderful.
