At first I was going to make a screencast of my time with Touchgrind for Mac. The plan was to impress you all with my sick laser flips and bluntside nosegrinds. But after playing Touchgrind for Mac for a while, I'm sure that anything I screencasted would be nothing more than a fails compilation. I am objectively and quantifiably horrible at Touchgrind.
Illusion Labs has built a reputation for itself over the years as a developer of expensive-but-totally-worth-it Apps. Their games don't sell for the going rate of 99 cents, but it's never mattered much because they've been so good. You may remember them from such innovative titles like the extreme sports game Touchgrind and innovative platformer Sway.
