If you're interested in graduating from LÖVE, try Planimeter's Grid Engine[1], which is based on Quakeworld architecture and comes with fully client-side predicted multiplayer out of the box.[2]
In that regard, it's a lot easier than Unity 2D, which doesn't. It also has commercial support, uses pretty standard de facto formats, like Tiled, for its levels, and has been in development for several years.
It's the most starred Lua game engine on GitHub to my knowledge.[3]
Planimeter also publishes lgf[4], which is a LÖVE 11.3 drop-in replacement which provides PBR support, among other things, out of the box for those concerned with advanced workflows.
