Yes, on my new phone I can get CM to load, but it soon allows down to the point of unplayability.
Rover, which comes with the app, seems to get stuck on the help menu.
Do you mean Rover’s Day Out? If you’re talking about iFrotz, that issue with the help menu, which affected other games as well, has been fixed for a while now.
I mean with the Twisty 2 app that’s still in development. Does Ifrotz support Glulx?
Yes.
Amazingly so.
It also appears to have a serious bug in it somewhere - I tried running The Gostak on it; the halpock loads, but when I tried to louk JALLON as the first camling, the interpreter crashed with a stack overflow.
