Super Hexagon, that ridiculously difficult and ridiculously awesome game from Terry Cavanaugh, received an update today that, among other things fixes input lag on a number of devices, notably the Nexus 7. That's been a sore spot for many of us since launch.
Also, the game should now launch faster, setup has been improved, and the legacy options button is gone. Plus, you'll find other bugfixes.
