Our upcoming online tower defense game will feature a different control scheme and we need your help and ideas. Keep in mind that the game will not allow you to upgrade your towers during the waves. Rather, you will equip your towers and placements before the wave starts. The different control schemes we are trying out are listed below. Please pick your favorite or offer a new idea. (note: for option #2 & #3, you will shoot using a power meter) Thank you for your help!
