lockOn is another release by Jph Wacheski of Iteration Games that can be described as shooter with weird psychedelic effects. Guide your ship around using the arrow keys and shoot at enemies with the G key. Shot aiming is automatic unless you decide to target the nearest hostile unit by pressing the F key.

A forward gun can be fired but the projectile's movement is decided by your own speed velocity and current travel direction. There are collectible power-ups which increases your weapon strength but whenever your ship takes damage it weakens by one level. Enemy ships which have been destroyed will turn into blinking objects that you have to pick up. If you leave them around for too long, they will respawn into new ships.
