Great but a couple things to suggest

First off I want to say that you guys make some fun games and I really enjoy the second heros and castles, so much that I want to complain about it. Just a few things that I think you should consider when you make your next update.
1. Bows/Crossbows/guns used by the hero should not be able to miss. You are already physically inhibited by fog and its not light using ranged weapons are easy to use to begin with. Your units already suffer enough and only being able to see a short distance it makes those weapons completely useless as it the player. Its unrealistic.
2. All equipment and ruins seem to be worth 1 Chrystal. H&C originally had different resale value based on rarity, why not anymore? Its annoying and almost as annoying is the inability to sell beginner equipment. I dont want Chrystals for beginner equipment but its annoying not being able to get rid of it.
3. Ruins dont give as good of bonuses and you cant upgrade specific character stats. This wouldnt be such a big deal if it were not for the increasingly difficult enemies. Although it is somewhat balanced because you can summon Heros I still wanted to address it.
4. Seriously? Banner men stand in front of the wall? And upgrading them doesnt make them cheaper like the goldmine sin the first game.

I know it seems like a lot but Im just wanting to let you know what I think is negative about the current game. Overall I really like it and there are many great Details and elements to the game.

Also, do you guys develope from scratch code or do you use a coding engine like unity?
