interesting all in all very good usability, the tutorial too long though, takes ages until you can do something yourself. the servers are not up-to-the-task, lagging, tasks are not being finished, you need to login everytime again to update said tasks... but that's the problem with free games, very cheap infrastructure. UPDATE: Now crashing after loading screen. I guess developers abandoned this game and try to squeeze out the most cash before it's shutdown. This game is dead.
