I'd like to suggest an option that freezes monster animations in their habitats to save RAM (it's problematic oon lower end devices I heard) and battery life on player's phones since the game drains it very fast.
It could be a button like turning sounds or music off in the parameters section and even though I know that's not the plan since the vault came out, it would allow to have more than 90 habitats.
I know monster animations are very endearing for new players but once you've been at it for over a year you get the gist of what they do in their habitats. It might also help solve issues on SP's servers end although my knowledge on this matter is too limited.
WHat do you think?
