I thought I'd give this game a little rest after an intensive 7DRL week, but as it happens, I've already done some improvements and experiments.
1. The suns now animate (flicker) in real time. This was a tiny patch but it looks nice IMO.
2. There are now transition effects to view level changes similar to the old FreeBASIC version. I first implemented them in Unicodetiles.js with a simple example, then put them into Infiniverse, noticed it didn't work, fixed it and voila! I think they really make the game much nicer.
3. I started experimenting with multiplayer. I didn't think I would do this yet, but couldn't resist the temptation, so I setup node.js with the socket.io module, hacked for around two hours and suddenly I had working multiplayer movement. Meaning X number of players can join and see others move around and even different view levels / locations are handled correctly.
Now even though it appears very stable (node.js is awesome!) it's a long way from being an actual multiplayer game as NPCs, collectables and missiles are not synced. In fact, the server is under 100 lines of code and acts mostly as a message courier, so it is also trivial to cheat. To make it properly, I'd need to put the server to play the game. That's going to be a big task, and also make the server more heavy.
Anyway, the latest dev version (with the new effects) is available for testing online @ here
Strictly speaking, it does contain the multiplayer bits, but I don't yet have a server running constantly.
