This is a template for CToH were you can create your own tower! To edit spikes, go to the "Spikes" sprite. To edit the ground, go to the "Ground" sprite You can select a difficulty and a name, but make sure to include if it has been verified (beat) or un-verified (Not Beat) Difficulty may be changed.
