To work towards a deployment on mobile devices, the aspect ratio of the game has been changed from 4:3 to 16:9 (576:1024 instead off 600:800). Together with new UI-widgets, this allowed to add more screen space, increase the distance between the gates and thus give the player more time to calculate the primes. To compensate the longer way, the maximum speed has been increased to 200%.

Instead of playing a fixed number of rounds, the player can now simply decide to play again with the same settings, or return to the main menu.
