There is ChoiceScript Saving Plugin (Update: Sept. 2019), which is supported by DD.
@sinnie I think JimD has been using something very similar to this system in his ZE games for a while now. May be worth a cross reference to see if there are any notable pros/cons across the two?
@cup_half_empty I’ve found a lot of heavy CS stuff slow on my phone too. I don’t know if that’s simply down to phone CPUs or if there is more at play here. @choicehacker 's racing simulator for e.g. isn’t very responsive on my mid-range android phone.
FWIW this seems to run fine on my phone though. Can’t see any noticeable slowdown in the linked demo.
