I haven't played on mobile so I'm not sure and I'm not really familiar with Twine but I just have seen text-based games like "First Taste of Freedom" or "Monster Girl Farmer" among others on itchio that has a save button off to the left of the screen although considering the different layouts that probably means it isn't made in Twine so I'm not sure.
thanks for that, they both look like twine games (first taste definitely is, in the more info it has twine listed)
there is a better engine i could use for my games using twine that would allow a save button and those games used that more popular and versatile engine, thanks, if those games worked for you that is another reason for me to switch which i have been debating for months now
