Requirements

• R5 - Non-trivial use of at least 1 plugin: I will use DOTween for animations and UI.
• R6 - Non-trivial use of Editor Extensions: I will create an extesion to tweak different parameters for procedural content generation.
• C5 - Extensive use of Artificial Agents (AI) and NavMeshAgents: The enemies will follow the player and navigate on the NavMesh.
• A1 - Implement Save/Load for your game. The user will be able to save their progress and load a previous save. There will be 3 save slots.
• A4 – Use procedural content generation: I will be using Wave function collapse to generate each level. The level will be divided into rooms. The generation will happen after the level is selected in the main menu.
