No, stock RPGMaker is somewhat compatible with mobile, but I use a bunch of custom stuff that only really works on desktop. Also, I don't want to be mean, but what's your situation that you have NO desktop, laptop etc? I understand needing to keep things cheap, but pcs ARE cheaper than phones. Corporate/school surplus stuff from 10 years ago (which is MORE than enough to play this) is like $80 on Ebay. You can get a monitor for $20 at any thriftstore. Unless you're buying second-hand, phones START at like $200.
How are you able to function without a desktop? How do you do paperwork, browse anything other than social media, write anything longer than a paragraph? A number of people have asked this, and the whole scenario behind it genuinely baffles me. If you're someplace other than the US, where the availability is different, fair enough, but it's not a cost issue. Are you a university student crammed into a tiny dorm? But then how are you doing your coursework? Is your living situation so unstable/dangerous that you're afraid anything not on your person will be stolen? What's the story here?
