I have a lot of fun while creating biomes for the Underkeep game. Each environment in the game is constructed from dozens of sprites, pixelated at a crazy high resolution so they look detailed even in close-up. Btw, the Rake in Grass team will release the game soon! #pixelart #indiegames

I have made new portraits for the Underkeep RPG. The demo is featured on Steam Next Fest right now, and if you like dungeon crawlers, you should try it! #pixelart #rpg #indiegames

Dnes v šest hodin vychází na Steamu moje 30 let stará prvotina COLONY 28. Původně jsem byl rezolutně proti vydání = hra nezestárla dobře, ale původní vydavatel mne přemluvil. Přes dávno ztracený zdrojový kód se povedlo nemožné, hra podporuje gamepady a Steam deck. Nostalgie 2800% #retro #indiegames

I love drawing monsters. They are sooooo cuuuute! This one was created for DRAWetc - the creative studio from the Czech Republic. The illustration will serve as a theme for IsThereAnyDeal pages.

You are entering the vast cave area. An ominous figure approaches from the shadows towards your party, mumbling unrecognizable words. What would you do?

Don't let the simple visual fool you! This is the heavyweight JRPG! What starts as a simple joke quickly becomes a deep social satire with existential questions, tactical battles, many side quests, and pop-culture refs. It all feels like Tarantino, Gilliam, and Aronofsky decided to make a game!!!

More bluesky cropcut experiments. Hopefully this'll look nice. NES background graphics, for project 'borscht'. Warm tones achieved with the PPUMASK emphasis bits.

Okay. NOW it’s finished. (See if you can find all the extra ducks I added to the picture too!) #pixelart #artpost #pixquare
A clearing in the forest, a small house with a red slate roof rests at the foot of a sheer cliffside, smoke billowing out of its chimney. A rough picket fence circles around the grassy clearing, while the entire area is overgrown with greenery (including all on the cliffside). The early evening sun shines through the distant canopy. There are now 8 ducks in the scene.
