Boxed Tower: Tower Defense

Your lone tower is under siege by happy, smiling cubes! They are coming in packs and plan to take down your tower! Place and drag your finger to shoot arrows at the invaders. Be careful, some enemies are harder than others! Collect gold and use it to buy powerful upgrades at the shop. But make sure to use them wisely! Your tower can only take so much of a beating before collapsing. One wrong move and its game over; back to wave 1. Plan accordingly and shoot straight! Can you beat all of the waves? If youre having trouble, let the crates reach your castle for extra gold. If you have any suggestions or feedback, leave a review and I will try to respond to you!
