- Sprites
- Initialize Tilemap (Yan)
    - Script --> World (manages access to tilemap)
    - Player is an object, not on tilemap
    - Multiple layers
        - Ground (Water, Ground) --> custom data (Walkable, Weight = 1)
        - Obstacles (Stone, ...)
        - Pickup (Berries, Trees, Boat parts) --> custom data (Type of collectable "tree", "berry", "boat")
        - Temperature layer (toggleable, types: normal and warm, transparent solid color)
    - Collect all "objects" from the tilemap on initialization in arrays/dictionaries for later access in the tree
- Design a tilemap for the game
- Player (Dome)
    - Stats (see document)
    - Inventory
        - with one slot
        - can pick up items from tilemap (Pickup)
        - can drop items back onto tilemap (Pickup)
- Navigation (Dome?)
    - Use tilemap layers to compute route
    - Support obstacles
    - Result must be an array of tile coordinates, length (array length) and the total cost (sum of weights)
- Decision Tree (Classes, etc.) (Luca, Cool in)
    - Reference Food Gatherer for implementation
    - Child of player, serves as controller
    - Script needs access to the scene, player and other objects/data
- Implement Behaviours
    - Implement all kinds of Behaviours, see document
- Visualization, make the simulation understandable
    - GraphEdit
    - Distances
    - Current navigation path
    - ...
