Really cool progress. Thank you for sharing your learnings and thoughts. Great commitment staying with this. On the carriage collisions point above, could you just add a collider and reverse their direction, or raycast from a spawn point and if there isn't any collision spawn them and they just move horizontally across the screen? Really great look and wishing you continued success.

Thank you so much! <3
I did have collision setup for them but the issue then is the size of the motion planning grid. Since the buggy is larger than the grid the NPCs just get stuck. I think my best bet might be to change the grid size if they have a buggy, or similar to what you said, flip the sprites if a collision is too close. Right now only it's only a 10% chance of spawning with a buggy so that one's gonna be a polish issue someday!
