Summarise your game!
Star Skuff is a Tower Defense game where the player builds towers and defends the base from enemies

Click on the construction points and build available towers
Click on the towers to upgrade them
You can move the towers by going to them and pressing the "Spacebar"
Start a wave of enemies with the "StartWave" button
You get a reward for each enemy killed and at the end of the wave
At the end of the wave, you can open a new tower for construction
After death you can click on the green respawn point and after the timer expires you will appear there

Please explain how your game fits the theme:
The interpretation of "Weapon" is that the player can get into any turret that can attack or support, so it makes him it literally a weapon.
