We've uploaded a small patch today that fixed a rare crash caused by changing some options.
We've also taken this opportunity to improve the alien movement on the very final stage, so the aliens now fly continuously, and weave around the mothership. Improving both the look and the challenge of the level. In addition, we've fixed another rare bug, where sometimes the final level would just loop, instead of increasing difficulty and returning to the first stage.
There's still a possibility that we'll have one more small update before Christmas, so watch this space.
Many thanks for your support.
