While there is no "Official" version on the Google Play Store, Android users typically access the game through one of the following methods:
Since the original game used keyboard controls (Arrow keys to move, 'A' to jump, 'S' to attack), you may need an on-screen keyboard app or a gamepad mapper to play effectively on a touchscreen.
Use mobile-friendly repositories like GetJar to find a version compatible with your device.
Download the original game file from the Internet Archive and run it using a Flash-compatible browser or player app.
The sequel introduced checkpoints, a new weapon mastery system, and the ability to carry objects without dropping your primary weapon.
