@Martin Fuze can be a wonderfoul way to get into programming and make some pretty advanced home-made games and programs which would work cross platform without any porting problems, it can be also a nice thing to start even professional projects and apps, maybe you can just release something like an xcode or visual studio plugin to support your language and the functions and then to have it compiled to an actual app, of course this means lots of work.
I personally will be just gratefoul to have fuze 4 switch ported to pc and available on steam to make games i can play on my pc and then on my switch and just transfer them using some sort of accounting or cloud. if you can make a playstation port and a mobile port supporting those features i mentioned it will be just as great.
This is just me dreaming of course, i hope in something like that to became reality but that's just me.
And since I know low level c quite well now, i was thinking about creating an interpreter in c and porting it to mac, dos and ios and maybe windows and linux, and so to have programs written with the interpreter's language to work cross platform without issues, the only problemating things will be just input support and graphics modes support and mediating all the platforms differences, and of course the dos port will be very challenging for memory management (requiring things like protected mode very likely and a math co to support things like floating point without mutch truble). Only thing i don't have now is the time to work to such project, but iot will be very cool to have.
