I really like this one! I beat it once the intended way and almost twice by rushing the boss, but I made a mistake at the end. Could use some balancing. Please make it so you can move when building with the mouse lol, even if just adding WASD keys for that. I had one crash to desktop that caused me to restart.
Adding a time element may help, say waves of reinforcements from the castle, otherwise I just sit and amass resources and spam turrets. I'm convinced that you can beat the game with just spamming the first chomper turret. Adding enemy resistances could fix that.
