I didn't really understand how to play the game. There where some things (mine and fields) which couldn't be placed for some reason and so I ended up building alot of spikes only to get a game over screen after an enemy died from them in wave 2?
The music was really enjoyable - it reminded me of Age of Empires II.
Unfortunately I also had some kind of bug where I would click not where my cursor was, but somewhere up right from it. Maybe this is because I'm playing on a higher resolution than 1080p.
With a little tutorial or at least an explaining text on the project's page it could be very fun.
