Use the mouse to move and shoot enemies. The larger and brighter the enemies are, the longer it takes to destroy them. Don't let them get to you or the bottom. If they touch the bottom, your base HP decreases. You will upgrade over time. Use the melee to get close to enemies. How long can you last?
