Bzzzt is a fast-paced "jump-dash-run" retro game with a fresh and modern design made almost single-handedly by one solo developer, Karel Matejka, known as Ko.dll.

Inspired by the 80's tech revolution, this beautiful pixel-art precision platformer transports you back in time with a brand new adventure, paying homage to the popular and much-loved gaming designs of the past.


What can you expect?

  • Pick a difficulty from casual to hardcore, and choose a gameplay style that suits you the best.
  • Enjoy extremely precise and intuitive controls.
  • Push your limits in time challenges.
  • Compete with others in global and friends leaderboards.
  • Experience rich environments with ever-changing game mechanics.
  • Survive and adapt your style for intense boss fights.
  • Optional permadeath mode.
  • Immerse yourself in the beautiful retro soundtrack made by Martin Linda, the creator of Rytmik Ultimate/Studio.


The year is 4096.

In a top-secret laboratory, inventive Doctor Emily and world-renowned Professor Norbert are working on a highly classified project. Through their joint research and intellect, they finally created a tiny robot with a big AI personality! No larger than a regular household toaster, but with some extraordinary skills, ZX8000 is ready to save the world, one platform challenge at a time!


Meanwhile, other dark influences are at play in the world of Bzzzt. The evil mad scientist, Badbert, prepares to unleash his nefarious plans upon an unsuspecting world as soon as he finds the perfect equilibrium of darkness, malice and madness. Bwahahaha.

Grab your controller or keyboard and navigate ZX8000 to complete his missions and thwart Badbert's evil plans!


Be the robot that rescues the world!

After four years of development, I have finally released my solo project!

BZZZT is out on Steam and GoG!!!


Be ready for the pleasant platformer challenge, over fifty stages, intense boss fights, upgrades, global and friends leaderboards and cute pixel art full of amazing animations.

The game has 100% positive reviews from over 200 players on Steam, sitting in 3rd place of Steam Hidden Gems, and it's getting amazingly high scores in gaming media!

"With flashes of Sonic Mania, Celeste, and Super Meat Boy, this out-of-nowhere indie gem might be one of the best 2D platformers I've ever played." - GamesRadar

95/100
Bzzzt is definitely everything I want in a retro-style platformer. It's fun with great controls and music to make you keep going even after 100 deaths. I cannot recommend this game enough. - GameGrin

9/10
"An incredibly addictive platformer with adorable graphics and a fantastic musical score. Its gameplay captivates newcomers and challenges experienced players alike, and if you aim to collect everything, you're in for a decent challenge." - Level

10/10
"České hry se alespoň u nás řadí mezi svatou kategorii, u které část hráčů těžce nese jakoukoliv kritiku. O to víc mě těší, když se po určité době objeví další výstavní kousek, jež patří do síně slávy a kritizuje se mi jen steží. Bzzzt je výjimečný titul a podtrhává to bezchybně zpracovaná audiovizuální stránka, kreativita, nápaditost a znovuhratelnost. Hra je dělaná s láskou k řemeslu, které začíná ve většině hrách čím dál více chybět a pevně doufám, že se od Karla Matějky dočkáme nejen pokračování, ale i dalších her." - Indian

9/10 ROBOTS
"Miren, genuinamente no sé qué me gusta más, si la jugabilidad, el estilo, la música o la manera en la que te transporta a los antiguos arcades, aunque ni siquiera los hayas jugado." - Charscueva


Karel Matejka, known as KO.DLL, is an artist who started his career as an illustrator and a graphic novel artist. Soon after he got in touch with the first computers, he started making games, which earned him the status of one of the first pioneers who started the gaming industry in the Czech Republic. His unique and multi-genre art style brought him worldwide popularity. Although his main passions are all art forms, he's also a coder, a game designer, a terrific chef, and a dedicated friend. And above all, he's a hard-working game lover with a dream to make games the old way again and pay homage to all the great games from the '80s that - like for so many of us - have formed his style and passions.

"If it weren't for the 8-bit computers, I would never have started making games. It was love at first sight. My feelings while playing these first games, that enthusiasm, that boundless amount of creativity, playfulness, and the utterly addictive gameplay of the 1980s, that's what I have channeled into my latest game."

"Bzzzt is a trip into the past, exactly as I remember it. With rainbow glasses and pixel art pumped up to the max!!!"
