Shirley's Revenge

You move left and right with the arrow keys, jumping between platforms while firing at enemies with the spacebar. A shield can be activated for temporary protection, usually with the control key. The main goal is to stop a threatening android from destroying the city, progressing through levels that gradually increase the number and speed of opponents. The pacing is consistent, presenting a steady challenge without being overwhelming. It feels like a focused, no-frills arcade experience from that time.
