If you guys really want to play on mobile, you can use Steam. Just install the game on your PC, add it to your Steam library (top bar Game > Add Non-Steam Game > Browse), then download the Steam Link app from the Google Play store and sync it with your PC. It requires internet access, but as long as your PC is on (and not locked) and your phone has internet, you're good to go. This works for any point-and-click game or anything with controller support. I use it all the time since you can add a magnifying glass that lets you see small text or click on small icons easier. Plus, it's Steam, no sketchy third party shit required.
Note: JoiPlay works too, but since these games can be 3+ gbs large, I don't like having them directly on my phone which is required for JoiPlay.
