Your body is the controller. Catch Flex is a dance rhythm game that tracks your whole body with one camera: no VR headset, 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 — boot the balls, or knock them 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 the moves differently, and your whole body plays, not your thumbs. VOL. 1: TEN HAND-CHARTED TRACKS Original dance music, 87 to 150 BPM: house, electro, techno. Charted for what a real body can do: everything within reach, no jumping. Play a few back to back and it's 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 — nothing to install, nothing to buy. Bring any song, chart the moves yourself, and load the level into the game. A level is a single file: open it on your device, or send it over your Wi-Fi from any browser, which is how levels reach a TV. You'll find the editor on the Catch Flex website. WHAT YOU NEED Room to move, good lighting, your full body in frame, clothes that don't blend into the background. If your device has a camera, that camera is enough. If it has none — on a TV or a console — the free Catch Flex: Controller app turns your phone into one over your Wi-Fi. Versus needs one camera or phone per player. Either way, the bigger the screen, the better every move reads 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. FREE TO START The first track is yours to keep — play it as often as you like. One purchase unlocks the rest of Vol. 1: nine more tracks, Versus and your own levels — no ads, no subscriptions, yours for good. See you on the leaderboards.
