Hi Devs, maybe you read this:
When a military unit is selected, highlight the corresponding barracks on the mini-map and in-game. This way, it's way more easier to send troops home for refreshing when you have 3+ barracks and troops. Currently the user must click trough all available barracks to find the one of the selected troop. Alternative: make a button in each troop-menue like "send home" or "training".
Water towers: Flow-in and flow-out is shown, but only for directly connected buildings. However, surrounding insulas which also drain water are not shown in this overview. They also reduce the available flow-out of a water tower.
Water inlets which are connected to a water tower drain water, even if there is nothing connected to this water tower (flow-out=0). This is tiresome if you build a dam and place the inlets before it fills with water. The inlets will prevent the water level to rise in the dam because they drain water even if nothing is connected. Also a solution for this: see #4.
When placing an inlet, place them on the ground level (not water level) or make a quick pop-up to let the user choose how high the inlet should be. I get the way it is now, is to be able to build multiple inlets with different heights (controlled by the water level at build time). But it makes no sense to partly flush a whole dam just to be able to place a water inlet not at the top of the water level in the dam.
I have all achievements, 104 h play time, currently building a city with ~12K people. Want to add that I love Nova Roma and that you did a great job! The terraforming and water mechanics are such an awesome extension to Kingdom and Castles.
