- Use W, A, S, D to move; Mouse to aim
- Charge your shot by holding down the left mouse button, shoot by releasing it. A faster bullet deals more damage.
- The blue cross guy is NOT your enemy; he heals you when close enough to you. Leeches will try to kill him.
- The goal is to collect as many yellow orbs as possible before dying. They will spawn at random positions, so keep moving.
