Roto Force is an amazing run-and-gun twin-stick shooter with incredible boss designs, great humor, and an ever-changing retro art style that blew me away.

The game is split into missions with 11 rounds of attacks that we must survive by defeating all the enemies and bosses. In each mission, we run left and right to move around on the inside of circular, triangular, or square-shaped one-screen levels. And whenever we move, the entire level rotates alongside us.

The left-side joystick is used for moving and to instantly dash to other sides of the level, while the right-side joystick is used to aim our weapons. And since some enemies have shields that we must break with a dash before we can hit them with our weapons, constant movement is incredibly important.

As we progress, we also acquire new weapons that instantly replace our previous weapon. Another neat feature is that we start with five hearts but can pick up additional hearts and use them as ammo for a charged-up super dash that destroys most things.

The gameplay is rather challenging, but we can always restart at the last round. In fact, the game can be as difficult or easy as you want. It has accessibility settings that make us invincible or slow down the game to make it easier, and for the hardcore completionists, there are modifiers that only unlock after beating an entire stage without taking any damage.

The boss designs are fantastic, with unique behavior and intricate attacks that even alter the color scheme of the game, creating a highly immersive experience.

Roto Force is free to try for the first mission, with a single $4.99 iAP unlocking the full game. So often, genuinely unique gameplay mechanics and controls unintentionally end up creating a bad experience, but that’s not the case in Roto Force, and that’s why I have fallen in love with it.
