Zones 20 and 40 now push everything rightward for the first 20
seconds of their chase, forcing the player to tap left to stay on
screen. Added a main menu (new game / continue / skins), an in-game
pause menu, and a skins system that unlocks permanent stat bonuses
(speed, damage, HP, crystal/dark-matter/droid multipliers) as the
player's max zone reached increases.
