A new build is up, with fixes for the most critical issues in the previous build (freezes and lost command gestures). Gestures should work more smoothly now. But while the move to html means a lot of power and flexibility, it comes with the price of not running as fast on the oldest and slowest of devices. I'll continue to tune to make sure it is acceptable even on those.
There are still some know issues, and I will continue to improve the iOS version until it's ready for release. Please report critical and new glitches here.
