Thank you for playing and for the detailed feedback. Having to bring the food back was a design choice to mimic a pheromon trail a bit because I did not have time to implement an actual system for that. My solution would now be to add an additional scout class that only does scouting and brings back the first unit of food from a source (or let workers scout when idle). I also did not have time to investigate why some single ants get stuck in place but the death spiralling comes from trying to avoid an obstacle while the food is spawned inside a collider. Here I could add a timer for the ant to ignore the collision and also make sure food does not spawn inside a collider.
