they should add contests for low level people that are under the level 40 or something because the higher level people win all the contests and then all the low level people win nothing and it is really ANNOYING
they should add something called a auto collect that u can turn on and off that makes it where it collects all your recorcess from mines and compact house when they full (only when u ofline)
u should be able to use like more than 1 worker on one tower to build or upgrade to speed it up so like if something took 15 hours for 1 worker to finsish u could us 3 and make it take 5 hours
