TL;DR. Please consider creating some tiles that the players could interact with. Not just containers. --- while posting about water towers, i thought that you can't really interact with the map objects. with this i mean that the map (at the current moment) is just a container of items. What about some buildings/entities that allows interaction ? a water tower could be used with generators to open the acqueduct again for some time, for example. A radio station ,with generators, could provide the players with some informations. Another kind of interaction: a lot of houses nowaday have a safe. Behind a picture, under the floor, etc. There could be such kind of items in some houses,the simple version of the interaction could be just "click and it changes the tile to the safe one". It could also lead to interesting considerations:if a more "evolved" interaction is planned, the ability of seeing the safe could be tied to a stealth skill ,that could improve the ability to see it based on the player experience. Also opening it could again be related to a "mechanic" skill, (that,i must stay , could be used for almost everything in a zombie situation )
