Your hand won't stop moving. Ghosts are swarming from every corner of the ocean, and you've got one job: draw the right symbols before they reach you. This is a fast-paced reaction game where you play as Momo, a magical cat who dives underwater to zap spooky ghosts by tracing shapes on your screen. Think of it like a spell-casting rhythm game meets whack-a-mole—except you're drawing lightning bolts and V-shapes instead of swinging hammers.
The concept is simple: draw shapes, defeat ghosts. But when five of them rush you at once, your brain starts sweating.
You see a ghost floating toward Momo. Above its head is a symbol—could be a horizontal line, a "V," or a zigzag lightning bolt. Draw that exact shape on your screen (mouse on desktop, finger on mobile) and Momo fires off a spell to vaporize it. Miss the shape or draw it too slow? The ghost hits you and you lose health.
Ghosts don't wait their turn. Two, three, sometimes four appear simultaneously, each showing different symbols. You need to prioritize—knock out the closest one first, then swing back to the others. As you descend through the ocean levels, they get faster and show more complex symbol combos. One ghost might need two shapes in a row before it disappears.
At the end of each stage, a massive boss ghost appears. These require drawing long chains of symbols—sometimes five or six in quick succession. Mess up one stroke and you have to restart the chain. Defeat it and you unlock the next ocean zone with new ghost types and even tighter timing windows.
This is for players who like quick reflex challenges but want something cute instead of violent. Kids will love the colorful underwater world and adorable ghost designs, but don't underestimate it—later levels get genuinely tough. If you enjoyed Google Doodle games or anything like Fruit Ninja's swipe mechanics, you'll feel right at home. Perfect for short bursts during a commute or when you need a 10-minute brain workout.
It's frantic but never feels unfair. The art style is bright and cartoony—think Halloween decorations mixed with a Pixar underwater scene. Ghosts have goofy faces, jellyfish glow in neon colors, and Momo's animations are adorable when she casts spells. The soundtrack is upbeat with spooky undertones, though it does loop after a few minutes. Visually, it's clean enough that you never lose track of symbols even when chaos erupts. The game doesn't punish you harshly for mistakes early on, but by level four, you'll be redrawing that lightning bolt five times because your finger slipped.
The game saves your progress automatically using browser cache, so you can close the tab and pick up where you left off—just don't wipe your browsing data. Performance-wise, it's buttery smooth even on budget phones. I tested it on an older laptop and didn't see a single frame drop. The drawing recognition is surprisingly forgiving too; your lightning bolt doesn't need to be perfect, just close enough.
A solid pick for anyone who wants a skill-based challenge without the commitment of a long campaign.
Responsive and accurate. The game reads your shapes quickly, though super fast scribbles sometimes don't register if you're too sloppy.
