Yeah, the main menu is just... Well, the best thing is that it is. And although it is better from what it initially was, it still is a far cry from what it should be. The in-game menus on the other hand will most likely stay the way they are (floating 8-bitsy windows) but there will be more stuff added there.
There will be more actual gameplay stuff coming in in following weeks. After I fix reported bugs and work a bit on improving performance for Quest, I plan to work on extension modules and weapon crafting. This should add more depth and strategy, although until there is an overall map, it will be lacking direction (well, it will be just random stuff).
