hi there! does the engine allow the possibility of battling other trainers? or is there a way to do that even in a "hacky" way?
Hello, of course you can battle other trainers! Did you play the demo? I'm not sure if the demo let's you get as far as battling players, but it's very possible yes :)
We even have an intuitive trainer editor that we just recently released that lets you make trainers and assign their monster teams. You can see a video of that here.
