Yesterday I got a multiplayer session up together with some friends and played a few maps. Again I must say I am impressed and really like the game. There is so much fun content and smart design, not to mention building a dungeon and watching creatures go about is really fun.
Despite playing on the two largest maps we had no problems with lag, desync or such. Network was rock solid! We didn't encounter any other bugs either. The only weird thing was that we felt creatures didn't really go where expected when using the call to war spell and we had trouble defeating an AI player because it seemed our creatures did nothing. Some managed to walk up to the Dungeon Temple, but they didn't attack or anything. Maybe winning is achieved in some other way?
We also didn't find a way to destroy walls. I can imagine this is intentional, but as things were now the only way to enter our opponents base was through a bridge build over a lava area. I doubt that is the only way to enter a base.
As for the call to war spell, I noticed on GitHub there is a commit that adds a symbol for when creatures are answering a call to war, so that is already fixed. I believe that is smart, since we weren't sure if creature responded when playing.
We also had to figure out what many of the rooms did ourselves, since I found only old documentation. After going through changelogs things became obvious, but a short list somewhere on the F1 Help screen would be nice. Besides that, the F1 screen was really useful when getting started.
Either way, amazing work with this game! If you want more feedback I can go into more detail about how these matches played out. Just tell me.
