Wow, first of all the art style is really stunning! You see the logo and think, that the game itself will be different. But no! Very impressive. I saw in the comment below that the game was made in 4 days. 4 days, my god!.. Maybe only one little nuance with visuals - walking animation looks a bit strange, is it because of resize?
Also music(and retro style sound) fits very well and really sets the mood. Are you an author or is it an asset?:)
The Game mechanics is good . When you just started you feel like "yea, strategy, roock!!". A small issue I met is hitboxes I guess - enemies pass each other in a situation where i thought the definitely should stop and attack, so it was difficult to catch a knight, when he goes on the top of the road.
Players below also mentioned that more units and upgrades will be nice, but as the game were made in 4 days its not an issue, I thnink.
So, anyway very cool! Don't drop it after the jam:)
