Note: The game is incomplete. I wanted to add much more.

Controls

• Use left mouse button to execute actions
• Use right mouse button to navigate
• Use mouse wheel to zoom
• Left click on a free tile to build a building; bottem right of the tile needs to be a free space or a road; some buildings are only allowed on special terrain
• Left click on a tile with a road sign to start building a road

Missing features:

• Story: Game should have started with the spaceship intact, and someone causing a crash. After repairing the spaceship, the same thing happens but they end up on a smaller world. The game would end when the slimes arrive at a really small world, where you can't really build anything.
• Resource management - buildings cost resource, buildings produce resources and slimes move them from one crossroad to the next
• Breeding - 3 slimes would breed and produce offspring, color would change depending on parents colors with some mutations
• Roads should take the color of the slime, if it's used often

Known bugs

• Slimes can move from one road/building to another road, even if they aren't directly connected
• 2 crossroads can be connected using multiple roads, slimes will only occupy the shortest road
• building something next to a road will add a road sign, but the separated roads don't get recognized by the slimes
