Okay so I recorded the game, overall it's really good and I like it. I think it can go further with more time beyond castles into like empires and stuff kinda like factorio if you've played that game. The upgrades do get a little costly especially with the stone I had trouble getting enough with the first stages and stuff. Also a little tutorial on your end goal would be nice just in case people don't read descriptions along with a menu screen. Other than that good game overall and I have given you a rating to push your game out there hopefully. I had troubles on my end via recording as I'm on a chromebook so I wasn't able to get the audio recorded.
