Whoa, that's pretty cool -- love the simplicity of the controls and the design, somehow moving around and interacting just all felt really smooth and good. I like the music a lot, and it had a fun pacing. It did almost make me want a game with similar style that was more of a slow builder though -- there was a lot of upgrades and resources all shown at once -- and me being the dum-dum I am -- didn't know not to just spend all my resources on knights immediately once I got to the first barracks and soft lock myself :)
But overall really intuitive and nice feel to it. Would wanna see it fleshed out more since it's just one of those games that feels good to control.
