Suggestions to developer:
UI/Interface:
1)the interface already great just need a little change:)
Performance/Graphics:
1)the graphics already good for low end device but you need to add graphics settings (because it become lag, overheating and choppy when the population is over 300) just like turn on/off the shadows or reduce the visual effects.
Bug/error problem:
- Please add "restore progress system"(you already know the reason)
2)bug report system need to add it(so player who encounter some bug can immediately report it)
3)add a solution to fix a bug/error if it can fix it
Gameplay:
1)Make wall do some demage to zombie(after upgrade it the wall do more demage to zombie)
2) Allow the citizens to build a trap around the city
3)the citizens can get infection from the zombie
4)the zombie can get enter the outpost and of course the sniper and knife fighter should able to push it(knife fighter also have a chance to get infection)
5)need a second base
6)this game will be more interested if have story or lore
(Waiting for you opinion)
