Not very well developed. I'm a developer myself. When you open smaller modals you see the previous modal in the background. This is a big minus from me. Loading times for most of the actions is very high, even if they are extremely simple requests. I play the game because I like the ideea a lot. Even if it is poorly implemented the idea is great. But, this is what you receive when you are cheap. You pay cheap developers, they deliver poor quality work.
