i like it. just wish i didnt have to restart the entire game when i get one wrong. maybe save progress, or allow us so many wrong choices (lives) before we lose?
most of the criticism aimed at your game is pretty much right on. the large avatar and huge hit boxes is making the game much harder than i think was intended.
the curve is a bit too harsh, we are just learning the game and its coming at us too fast. also maybe allow us to place turrets before the wave actually begins?
