I have some information:
Android game saves work perfectly on PC (I guess vice versa), I started on phone, but the buttons were very small, ( unreadable) I couldn't even see what was written on them (Huawei P30 , I guess it has normal screen size.)
Personally I liked the first part better than the engine, both for the technical execution. I hope in time the second part will reach the same level.
I first tried it at the beginning and just picked it up again after a few months. I can see that the story is getting more complex and more characters are being added, but I still think it needs technical improvements (Sounds, animation etc.)
I say this as the first part was my favourite and has forever written itself in my book as one of the greats of f95.
