Sorry for necro-posting, but I would actually answer to this question: as I have promised I'll support Android by PGE Engine to play SMBX episodes on phones and/or tablets, and, it's now present! You can try the experimental version of PGE Engine by yourself:
https://wohlsoft.ru/pgewiki/PGE_Engine: ... ion_(2019) I mean, not because the main game core is WIP, I mean the overlay for Android id WIP, it needs the ability to ask disk read/write permission on Android 6+, and I need to make the configurable touch screen control buttons, otherwise, they may suck on some cases in current form. However, try out the thing on your own risk!
I had to chop Qt from PGE Engine otherwise, it conflicts with SDL2 on Android. So, that was made. Next step is attempting to figure out how to compile and deploy SDL2 projects for Android, and this also made. Next bigger step was polishing and debugging the stuff to allow using Engine without danger to stuck because "some button didn't implemented", and after I have made touch controller to play games with no having USB-OTG keyboard or joystick which may not be supported by certain device, or obviously, no guarantee you'll have USB-OTG cable or extra keyboard or gamepad that will work on Android device... So, the work was done, and it's an experimental but playable engine which works on Android!
P.S. A video I have made for that:

P.P.S. When the Android overlay will be polished as it will be "fine" (when you'll be able to use it simple and easy without of extra effort to put files on your phone/tablet), then, I'll post it together with a next stable PGE-Project release.
Note about Editor build for Android: it sucks, and, in most of cases it's a totally mess. When it's needed to have Editor on Android, then, it's better to build totally separated UI for mobile devices and touch screens, otherwise, desktop UI is a mess on mobile touch screens. So, for now, it's much more reasonable to have Engine only on Android phones yet. Editor on mobile is more just for fun rather for professional work.
