The gameplay itself is fun, and it looks nice, though all of my gameplay sessions have ended with everything in the game losing its correct texture and turning a strange pearly rainbow of colors and then not responding, albeit I do usually get 30 minutes to an hour of playtime before that happens. Anyway, after having some issues with battery life for a full week, I looked at the processes running on my computer, and this game had left a zombie process open that is not listed in the Force Quit Menu or displayed with an icon in the Dock. It was eating up half of my CPU and a ton of memory and ostensibly doing nothing. I had to SIGKILL it just to get it to stop. They have some serious issues to address in the Mac port.
