Gotcha, I can think about some kind of paintbrush style of placement with touchscreen controls.
While cold, they have a high chance to shiver, which is an 'unproductive' action, and effectively wastes time. So keeping them warm makes them more efficient. Speed boosts are from mushroom spores and roads/terrain, currently.
Do you mind me asking what kind of phone you're using? Would be very helpful to know the hardware that ~100 population is a soft limit for, as optimisation is still a general problem. Thanks
