So about flatten terrain when you select area u dont know how literally it changed ( you can predict at some point) sometimes you think its will lift up but it make lower down.
My idea is can u add on selecting area (just on time when you controling it with the cursor) somekind “pointers” which will indicate how it changed in future like green pointer up when it lift up and red pointer when it lower down (if it changes really hard like will extend too far up then its show 2x green pointers up). That thing really helps to predict how u need chenge for the desired result.
PS. if there is something wrong with the text then don’t kick me, I used Google translator
For terrain modification i suggest this mod, but there can be some negative side effects - it is suggested to save before any big use - especially while people and houses are on the ground:
Other mods that i tried out and i think make the game at this stage more fun:
Better Camera and FOW
Relocate Resource
RaidersDropLoot
Tower Defense
More Compost Yard Workers
Winter Labor
There are some others too but i have not exactly tested them all. But as the game is not optimized yet - i guess it is ok to test a lot of stuff and have fun.
