Ill have 3 suggestion that might be you feel heavy.
1.low the price of item shop
If you make it lower,more player purchase item on shop.better then you make it expensive.
2.sensors are required
Lot's of player begin toxic and reporting them not the best way to do
3.private monumen's
Some player deside to wall the monumen's like gas station,lumberjack or miner.more crazy that some player wall power plant and city.even the roads block the wall,but someone have find idea to block the roads with statue between the wall.pls make road sistem's block everything on the road,so players can use the monumens for more recourse.
I'm telling this not for my self,but for everyone and developer.
Dev,i promise if you do this.more player will download this game and new player more comfortable to play🙏🏻
