I put "Singleplayer-focused" mainly because I thought it would be strange to play this on a server with random people.
I forgot that you could also play this on "LAN" or similar. Thanks for mentioning that.
Perhaps there will be more multiplayer support in the future :-)
Thanks for the thorough investigation! When I posted this I didn't expect people to get past the initial hurdles, so it's been great to see someone do a deep dive into the mechanics. I have some ideas to solve a few of the issues I've seen mentioned, so hopefully a post-jam version can make the game a bit more smooth.
I haven't yet figured out how to turn this into a popular game though, but I'm already well motivated to investigate ideas. :-)
The original idea was to have a progress tracker per player that tells them which building to build next. (with pictures of course)
The first would be the low altitude fireworks, then high altitude, then first altar and so on.
But, I'm sure having more buildings early would be nice. Perhaps some kind of utility buildings like teleporters or something?
Indeed, the instructions should have been ingame.
I just didn't have the knowledge, nor time to aquire it, for how to make a formspec with instructions.
It's definately at the top of my wishlist. :-)
About copying buildings, the first altar is simple and that's kinda intentional. A bit like making your first pick-axe in other games.
Later buildings provide more of a challenge, especialy if you want to figure out an efficient way to build them.
