Thanks everyone for the great feedback, especially @amras0000 (I really liked your detailed criticism)
I must admit, I kind of forgot about the generator image, and I had to rush them in the end. I would liked to have made them maybe more like a power plants, than generators but this works as well.
The X's could have been just drawn (I rendered them in blender as I did with all graphics, just though about adding more "pop" to it. But you are right, since everything was minimalist, they should have been as well.
I didn't get much time to playtest the game, and I would like to have made some different system for task generation. As it is now, there is a timer that ticks (different time for every map) and every tick it just finds a random building and tells it to generate any of the possible tasks for that building type. It was made just for testing, and because the lack of time, it ended up in the game. Maybe a better system would be the one that is aware of all the current tasks and creates tasks based on them (for example sometimes after catching criminals (police station task) the hospital would get a surgery task, or something similar). Also more tasks would be interesting.
Also I don't think the generator types were all that interesting, I would like to have made them more "unique" as the risky generator.
For some reason, my description keeps changing, and removes the screenshot, I don't know what is going on with that. If anyone knows please post answer in the comments.
Anyway, thanks for kind words everyone :)
