Bubblarium fills your screen with a beautifully animated underwater world: colorful fish drift past, a dolphin leaps above the waves, crabs scuttle along the sandy floor, and bubbles rise gently toward the surface. Tap any bubble to pop it, or just sit back and watch. TWO WAYS TO PLAY Zen Mode is pure relaxation. No timers, no pressure, no score. The aquarium runs as a living screensaver you can interact with whenever the mood strikes. Pop a bubble, watch the shark prowl, spot the UFO abducting your fish — or just let it breathe in the background. Bubble Rush turns the aquarium into an arcade challenge. Race the clock and pop as many bubbles as you can before time runs out. Combo chains multiply your score. Special bubbles — golden, pearl, danger, and mystery — change the rules on the fly. Watch out for the shark, crabs, barracuda, and UFO; they all have their own ideas about your bubbles. THE AQUARIUM IS ALIVE • Sharks prowl and snap at bubbles, costing you points in Rush • Dolphins leap above the water and dive back in • Crabs scuttle the floor and occasionally grab bubbles mid-swim • A barracuda darts through in a flash • A UFO surfaces and beams your bubbles into the sky • Angelfish, neon tetras, and seahorses drift through it all BUBBLE RUSH FEATURES • 8 difficulty tiers that unlock naturally as your lifetime score grows — from Reef Rookie to Bubble Legend • Golden and pearl bubbles worth bonus points; danger bubbles that punish careless pops • Mystery bubbles that trigger random events: score multipliers, bubble bursts, shark frenzies, and more • Combo multipliers for rapid pops • Game Center leaderboards and achievements • Round summary with stats after every game MAKE IT YOURS! Customize the scene from the menu: toggle creatures on or off, adjust fish count, bubble count, and crab count. Everything is saved so your aquarium always looks exactly how you like it. OPTIONAL ADD-ONS (one-time purchases, all $0.99) • Additional submarine scenery and a sunken shipwreck for the aquarium floor • Game Sub Pack: a navy submarine that patrols during Bubble Rush and fires torpedoes at your bubbles • Torpedo Pack: unlocks upgraded and danger torpedo variants for the game sub • Squid Pack: a squid drifts through your aquarium and hunts bubbles during Bubble Rush All add-ons are optional — the full Zen and Bubble Rush experience is complete with no additional purchase required.

Features
Read full description

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.
