- WASD or Arrow Keys - Movement
- Left Mouse Button - Select enemy to draw materials from. Ends Shooting Mode.
- Right Mouse Button - Select enemy to inject materials into. If too many materials are put in they will explode. Ends Shooting Mode.
- Space - If the syringe contains materials, attach the syringe to the player. If the syringe is already attached to the player, shoots materials towards the mouse cursor until materials run out.
You command a floating syringe, which follows your commands for as long as the player is alive. The goal is to take out as many enemies as possible. Keep in mind that with more destroyed enemies comes more enemies to take their place, and possibly unique variants. Last thing, Hit an enemy bullet 3 times, and it's game over, so make sure to watch your surroundings!
