Yeah. I have been thinking about it. It'd require a different sprite visualization and there's some weird edge cases, but it's how SimAnt and others like PocketAnts handle their underground perspective (https://thekingofgrabs.files.wordpress.com/2018/07/sim-ant-s...)
There's this game, Oxygen Not Included, that tackles the issue with ladders. https://assets.rockpapershotgun.com/images/2019/08/Oxygen-No... I know ladders are immersion breaking, but was thinking maybe ants could form living chains or something, idk.
