Hello!
The game is stacked with various plugins and somewhat limited in standard RPGMaker features (such as click-to-move). I'm not sure whether it would be possible to play it in a browser. I can try to look into it, but we haven't really made it with that possibility in mind.
I believe I saw a screenshot of someone using JoiPlay to play our game on a phone. It was the old demo version, so even there we can't guarantee that everything works as intended, but you can try that if a phone is your only option.
