I think it's a pretty cool game and it's very fun to play against the AI. It took some time understanding what's exactly happening, and I wish there was a little more instructions telling what's going on.
For example, maybe it's just me being dumb, but I don't really know when I have to manually upgrade my castle.
EDIT: I AM AN IDIOT. the game shows stars above the castle when you can edit your abilities. My fault, sorry about that game developer.
The game is pretty fast and I think a pop up would've been nice to tell me that I can upgrade stuff. I keep on running off, when I should be upgrading my castle. I'm also a little confused on how much health I have left, and I can't tell if the enemy base is about to die or my base about to die. And the health of a unit is pretty unknown. So some polish would be nice, especially since some audio cues to announce if something is happening would've been quality.
Otherwise the game is fast and fun, and I enjoy stream rolling the AI. I like how original the concept is and even with my complaints (which are honesty just nitpicks), capturing bases and attacking the enemy with my troops is addicting. I see more of a League of Legends than RTS here (minions summon occasionally to attack enemy base and controlling a hero that can be upgraded to become more powerful...), and it does feel satisfying capturing bases. The game play loop of getting heroes to claim territory, dying, then coming back is quite satisfying. Even if sometimes I have no idea why I won or lost.
So a solid game that just needs some polish, and I agree with all the other comments posted so far,
