Below is Andy's montage of our world maps and level art! Each of our islands will have its own tile set to help uniquely style it. Each level on an island will follow the island's style. This should help make the game feel varied and consistent :-) In the below images we have each island map followed by a level from that island.
We are able to have this many tile sets as we are targeting the 128k ZX Spectrum for Gloop Troops 2. The extra memory is being put to good use to store all the tile set variations
