We were a little bit worried about the weird AI implementation I made (to avoid using navmeshes because in the beginning of the project it was possible we could have some things changing on the terrain aka new colliders the AI isn't aware of) since that was the thing taking the most resources on CPU/RAM.
For the UI, well the main menu is customized a little bit but the rest is the default Godot UI ^^ Otherwise the textures were made by our awesome pixel artist!
