1) Grenades and such are fine, but please, just add at least a second gear slot, e.g. at survivor level 10 (or 15?) - there are tons of interesting gear items in-game! Just like riot shield+1h-weapon is an excellent idea to diversify weapon equips, a 2nd gear slot would allow many interesting combinations and more char customization.
2) We definitely need a stance/tactics slot: so scavengers could be set to "defensive" and not run into zombies, reckons to "keep distance", fighters to "follow" or "protect" etc. Some special tactics could be unlocked - e.g. via equipping skill books in that tactics slot ("heal in range" for medics). Controlling a group of survivors one by one is a bit chaotic.
Bug: had 200 storage, started upgrading it (1h, to 250 capacity), started removing junk (6h, 250 units), went offline. Normally, I'd get 250 storage first, then all junk would fit in it. But I only got 200 units after coming back online - so the offline order of completing the tasks is wrong.
If I build something (e.g. storage) before I get a mission to do so, it's often impossible to finish the mission without demolishing the building and re-building it. Mission counter should look for existing buildings instead.

Well, most people don't realize that the original KB game was created 5 years BEFORE the first HoMM - in 1990. And yes, it already had that battle mechanics. Also, same publisher and game designer for both original titles :-)
So, another game that you can't play more than 5-10 minutes at a time. Which isn't bad a priori - see already mentioned Elements or DreamWorld. But here, more energy with lvl-ups is actually a lie: you get a bit more, but the net gain is minimal or even negative. Every time attacks start costing an additional energy point, it's +10 total energy cost for 10 attack you can possibly make. But you get less, much less energy pool capacity per lvl. There is no positive progression, no improvement for me as player. It actually becomes less and less fun. An action should be an action - 1 point. Stop abusing our time as buyable resource and main profit source - it leads nowhere, really. It ruins every other cool gameplay idea you've spent so much time implementing.
