A lot of work went behind this version. We've wrapped up things feature-wise and have been focusing on stability, performance and playability. The game is now running smoothly at 60fps even on our lowest target device (iPad mini).
Most of our current levels have been re-worked to have more complex and interesting puzzles and of course we're working on new levels daily. We will be adding more graphical assets and new enemies still, but no more feature creeping is allowed!
