Hi, these are some bugs and suggestions that I found during playing the game. Hope this help:
1. Quick save: since later stages (especially 6 waves mission) can take more than 2 hours, it's a good idea to add some kind of save features. If you don't want player to be able to reload game (in case of screws up), then just delete the save after loading.
2. I've wrote this before, but during sandstorm, all turrets are knocked-out despite having tons of both electricity an stored power. Also, when the batteries inside turrets run out, they're also knocked out despite clear weather and having tons of electricity (and stored power) available.
3. Truck priority. AI's truck could have some tweak, or perhaps you can add some priority options (on the garage or truck). I have tons of trucks and roads, should be more than enough to keep entire economy going. But despite that, the truck keeps delivering ores and food, which is good, but they neglect the fertilizer plants (they keep it empty for too long time) even after crossing the plant multiple times with empty cargo (the waste plant and fertilizer plant is very close each other and can be traveled in one go).
You can add options so a certain truck is dedicated to certain facilities.
4. Keyboard shortcut. Like R for road placement, C for community center, etc. This is important during wave since we can't pause and we need to be fast.
5. Ability to undo last action. So when I accidentally place something in wrong place, or bulldoze wrong building, I can instantly correct my mistake.
