I played for a few hours while ignoring the less optimized gameplay, as others mentioned here, but I have another big big issue: I had to restart my computer and the save was lost completely.
With the amount of grind there is right now, I'm not touching the game until a future update addresses some of the points.
The artwork is very nice (for me), the gameplay is good too, but definitely needs a lot more work on rebalancing.
I only reached the progress that I reached through auto-clicking, otherwise my units are simply useless (tried the mage, tried the crossbowmen, tried the archers... all equally bad even with upgrades).
Looking forward to the future :D
