A tower defense game that requires 360 degrees of awareness. Spin your ground to have your defences engage the evil aliens in battle.

You play as “Turner” and have been recruited by the General Agency for Military Engagement “GAME”. Identified for your incredible gaming skills, they are putting you through a virtual training program about commanding a Settlement Placed In New land or “SPIN”. If you complete the training successfully you will be granted a full time position at Game. Perform well and don't blow your cover, so your friend Revvy can deploy his ROLL, Righteous Officer Legalizing Life. Since the SPIN is actually a TWIST, Targeted War Instrument Starting Trouble. 

Instructions

Spin the rings to angle your weapons to the incoming enemies. Towers shoot at enemies in their firing cone. Traps kill enemy's on touch. Walls bounce enemies away.

A and D allow you to spin the rings.
W and S allow you to switch between the rings

Building is done between waves by dragging weapons from the shop to the build points or buying upgrades out right.
