MOGIZ

🎮 Play now

MOGIZ is a 3D indie game where you play as a mosquito and drink the blood of a whole family. It runs free in your PC browser with no download.

Born in a swamp in the grass, your mosquito slips into the house through a torn window screen. At mosquito height the sofa, the table and the people all look like giants. You choose who to bite first: the cat, the dog, the baby, the high schooler, mom, dad or grandpa.

Fly close to skin and a red ring shows up, then stab. While you hold the button the blood climbs up your needle, your belly swells red and the bite swells too. When they twitch and raise a hand, pull out and fly. A full belly makes your wings heavy.

If you get away they come looking for you. The high schooler swings an electric fly swatter, mom sprays bug spray, dad claps and lights a mosquito coil, and grandpa grabs a fly swatter. Buzzing around their ears gives you away too.

A mosquito only lives for a day, so a few seconds after you die you are reborn in the grass nearby. Every rebirth you pick one of three evolution cards and become faster and smarter, and your bites swell less. There are 30 cards to collect in the dex.

Drink the blood of all seven in one life, fly back to the swamp and lay your eggs to see the ending. It tells you how many times you died and were born again, and you can save or share your result card.

On PC you fly with WASD, look with the mouse, go up with Space and down with Shift. Hold left click to stab and drink, and press Tab for the dex. On a phone, turn it sideways, fly with the left pad and press the stab button on the right.

FAQ

Do I have to bite them in order?

No. You can start with any of the seven: the cat, the dog, the baby, the high schooler, mom, dad or grandpa. The cat, dog and baby are easy, and from the high schooler to grandpa their hands get faster and they search longer for a mosquito that got away.

What happens when I get swatted?

A mosquito only lives for a day, so a few seconds after you die you are reborn in the grass nearby. The blood from that life starts over, and each rebirth lets you pick one of three evolution cards to become a faster, smarter mosquito.

What changes when I am reborn?

The evolution cards you pick keep stacking. There are 30 cards such as Wing Muscles, Numbing Needle and Compound Eyes, and 6 of them are gold. Each rebirth also makes the bite swell less, so people feel less itchy.

When should I pull out and fly away?

While you hold the bite button, the blood bar fills and so does their itch bar. When the itch is almost full they twitch and look at the bite. When a hand comes up, let go to pull out the needle and fly.

How are the people different?

The high schooler swings an electric fly swatter, mom sprays bug spray, dad claps and burns a mosquito coil, and grandpa uses a fly swatter. The baby only kicks in its sleep and bounces you off without killing you.

How do I see the ending?

Drink the blood of all seven in one life, then fly back to the swamp in the grass and lay your eggs. The ending shows how many times you died and were born again, and you can save or share a result card with your rebirths and the blood you drank.
