Screenshot Saturday update:
New tutorial level:
Updated some tiles and colours in Ruins:
Updated tiles in Desert, and sort of explanation of how the Desert's gimmick works.
When one player moves, his whole layer scrolls with him, but does not affect the other player.
This means that blocks that interact with both layers can be seen twice:
Update to the demo version will go up soon too, with updated tiles, slightly updated layout, and with slightly closer to true fullscreen mode (will detect if your screen is big enough for 3x or 4x zoom and adjust accordingly).
