I like the idea of the castles, but the problem with it is how to make it.
We can throw a castle building (stat) and call it a day.
Or we actually have you manage multiple castles with their own stats resources denar generation etc. Which would increase the management overhead for the player, but also we would have to change things even more fundamentally than the now removed army stats.
I am not saying it can't be done, just that it would take significant time maybe even making the game from scratch.
Also on another note, we've reduced the time it takes to train units and increased the amount you can queue. We'll continue to adjust these.
I did just see that you can now make more units faster. But this just speeds up the infinite march to nothing. I'm just going to build more walls and defensive units with fewer clicks. It would still take a couple of weeks to build them back up to where I have them right now so I'm not going to risk them attacking especially because anyone else playing is also creating more units (and probably much faster than I am because I sleep lol). And again, it is possible that this game just isn't meant for me, and that is ok.
This might just be something to keep in the back of your mind if participation dwindles and no new players join. What you have done from scratch is absolutely amazing! I would consider this a success but if you want to build something much bigger that really catches on, maybe you can take what you have learned from this one and apply it to your next project.
