I actually think it's pretty good. The map is also very detailed (although I think there should be some secret or secondary objective so you don't just have to go to one place to complete the mission)
One complaint I have is that there should be some indicator to see the missions (because sometimes I get a little lost in the map and forget what mission I had to do XD)
Although other than that, it's very good, I hope to see what they put in the next update
