So this is written in c# and can be transcompiled to JavaScript... Is there any public servers that will host your world? My daughters play minetest and love it. However, they each have an old reconditioned laptop, and their shared world is hosted on one of them, so that laptop has to be on and running minetest even if only the other wants to play and create. A browser-based world would be so much easier.
