Hello and thank you for playing my game - glad you found it to be fun. Personally, I wouldn't be comfortable joining an unknown Discord server, so if you need to get a hold of me, just write any concerns in the game's comments or ping me on Twitter/X (my username there is @The_M13Immortal). I don't think I would be up for doing a collab project, if that's what you're asking. Thanks!

Sure, I'd be happy to assist.
I used Unity Gaming Services (UGS) for my networking - it's easy to use and has a generous free tier, so it likely won't cost you anything. The relay servers do provide some lag, but it's certainly acceptable, especially if your players are geographically close together. I'd recommend watching these tutorials to learn more - they're lengthy but they cover pretty much everything.

Note that I did have to use some "outside the box" solutions to get everything to work as I desired. For example, I had some issues with jitter when using the built-in NetworkTransform, so I ended up programming the solution myself. Programming an online game can be confusing at first, but it's easy once you get the hang of it. I would recommend that you simply play with it for a bit so that you understand exactly how it works.
I hope this helps, and I wish you luck with your online game!
