Your body is the controller.

Catch Flex is a full-body rhythm game that tracks you with one camera: no headset needed, no gamepad, no wearables. Even the menus are gesture-controlled, so you never touch a button. Stand up, clear some space, and dance to the beat.

MOVE TO HIT

• Slash: cut blocks in the arrow's direction
• Catch: snag rings with a hand or foot
• Kick: send the ball flying, or knock it back with a hand
• Stomp: hit the floor marker right on the beat
• Slide: ride the trail to the end
• Dodge: duck, lean, or step over obstacles

Every song mixes them differently, and your whole body plays, not your thumbs.

VOL. 1: TEN HAND-CHARTED TRACKS

Original dance music, 96 to 150 BPM: house, electro, techno. Charted for what a real body can do, all of it within reach, with no jumping needed. Play a few back to back and it is a workout.

Not chasing a score? Switch on no-fail mode and just move through the whole song.

SOLO OR VERSUS

Chase the global leaderboards on your own, or go head-to-head in local split-screen Versus. Achievements track you from your first song to an S rank on ten different tracks.

MAKE YOUR OWN LEVELS

Catch Flex Editor runs in your browser, free, with nothing to install. Bring any song and chart the moves yourself. A finished level is one file: open it on your device, or send it over your Wi-Fi from any browser, which is how levels reach a TV. The editor is on the Catch Flex website.

The game also reads charts saved in other common level formats, so a library you already have can come with you.

WHAT YOU NEED

Room to move, good lighting, your full body in frame, clothes that don't blend into the background. The free Catch Flex: Controller app turns your phone into the camera over your own Wi-Fi, and that is the setup we recommend. A webcam works just as well if you already have one. Versus needs one phone or camera per player. Either way, the bigger the screen, the better every move reads from across the room.

PLAY IT IN VR (EXPERIMENTAL)

Put on a headset and the track wraps around you: the blocks come at your hands, the balls at your feet. Catch Flex VR runs through SteamVR on any OpenXR headset, and a Quest reaches it over Steam Link or Link. The headset and controllers carry your head and hands, and your phone keeps tracking your legs, so kicks, stomps and slides play as they do on the flat screen. Pick "Catch Flex VR (Experimental)" when you launch. It is experimental: the legs follow a phone camera and can drift, and every report helps.

STEAM DECK

Plays on Steam Deck with your phone as the camera and nothing to change on the Deck. Dock it to a TV and every move reads better from across the room.

BODY TRACKING STAYS LOCAL

Tracking runs locally, on your own hardware, and camera images are never saved or uploaded. When your phone is the camera, only movement data crosses your own local network. The video never leaves the phone.

PAY ONCE, PLAY FOREVER

The ten Vol. 1 tracks, Versus, and the levels you make yourself. No ads, no subscriptions, yours for good.

Not sure the tracking will like your room? The free demo has the first track, no time limit, the same game and the same tracking.
