Hmm, not sure why "Weed Smoke Willie" would require any of that? It looked like an interesting game, though - I hadn't appreciated the idea of fishing shark with weed, before.
For sure it doesn’t utilize any network stuff now, but it would be super easy to add a couple more Willies in there. But definitely considering adding an optional client side only thing for single player games
I love the concept of multiplayer-first without needing intricate networking knowledge. I'm actually working on a similar system for old retro games.
However, the demo games you have come across as too trivial and trashy to really show off what your system is capable of. I highly recommend putting a lot of effort into making something that shines there.
