> For your other suggestions, I think they sound like reasonable changes. Though to be honest, I’d probably need some sort of playtest to fully understand their implications on gameplay.
The code still needs a lot of cleanup (and there’s currently some oddness with the tooltips), but this should serve as a prototype for the proposed changes to pressure and temperature tolerances.

> \## Summary by CodeRabbit
>
> \## Balancing
>
> \- Rebalanced temperature tolerance speed bonuses and pressure tolerance health bonuses.
> \- Environmental tolerance effects now scale progressively with adaptation quality, providing smoother bonuses as microbes approach ideal conditions.
> \- Perfect temperature and pressure adaptation now grants the maximum adaptation score.
> \- Temperature and pressure tolerance ranges have been adjusted for more accurate environmental adaptation.
> \- Temperature calculations now correctly respect settings that exclude positive bonuses.
>
> \## Editor
>
> \- Updated tolerance sliders to reflect the revised temperature and pressure ranges.
