Hey there Retro! I played your game for about one hour, and didn't finish it. But I have my reasons for such, that I will say on my feedback below! I played more or less until when skeletons start appearing, I believe it's when you start to explore the tunnels.
From what I could experience, I can say that it feels like a good clicker game. The RPG elements don't feel forced, and actually reinforce the loop of click -> buy upgrade -> click -> buy upgrade -> ... . From the description of the game -- " Build up your farm as it grows into a town. [...] " --, it sounded very interesting.
Then, the why I did stop playing: two bugs.
--The first one is that I couldn't sell Bronze Pieces to get Copper Pieces (the inverse, selling copper pieces to buy bronze ones, worked fine). So, at first I thought that buying a high value coin would be a good choice, but later in the game I noticed I couldn't do the inverse, and got stuck, since I had no money to buy upgrades, I couldn't get more money because the storages where full.
When I tried to sell the BP to get the CP, the following message appeared on the console:
Exchanged -1 Bronze piece(s) at a market rate of -79 per Copper piece(s).
While when selling CP to the BP, the message was:
Exchanged 1 Copper piece(s) at a market rate of 111 per Bronze piece(s).
I guess it might have something to do with the minus sign? I don't know.
--The second one might not be a bug: it happens that I could not craft any equipment. I guess I needed to click, or click and drag, but it didn't work. Also, I'm pretty sure I had the materials. This is not a game breaking glitch, but I believe it severely impacts the tempo of the game, and that is why I stopped playing.
Oh, and I'm using Google Chrome 63.0.3239.132 64 bits. Maybe that has something to do with these problems.
Continuating, in my opinion you could try make the game more fleshed out by expading on the RPG part. The clicker elements could then become kind of a way to break the constant battling, or a way of supporting the RPG part (like hiring better Blacksmiths for your city: however, you might have implemented this already and I just didn't get to it yet. Monster Hunter does something like this.).
Also, if you want to raise the difficulty and make the game more rewarding using the battles, I highly recomend checking out the Shin Megami Tensei 4 battle system. It is outstanding: extremely hard, but very, very satisfying once you understand the mechanics. For example, even low level monsters can kill your party if you are careless; however, the opposite is true, that is, the player can defeat high level monsters if plays correctly. Searching for "smt4 battle system" will give info on it.
I guess that's all I can say for now. When the problems I pointed are fixed, I believe I'll play it again, since what I saw during my short gameplay was nice!
