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

Yes. It's inspired by Lovecraft a lot.

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?

I feel that 2D platformers struggle to find their place among players today.

Mech design? To be honest, I don't know what I just drew. Let's say, it's something sci-fi :) #pixelart #pixelartist #indiedeveloper #solo_dev

In my head, necromancers (or sorcerers) are not raging beasts :) But maybe you are right - maybe there is "something" missing. Perhaps changing his pose to show him casting a spell, and adding some raised zombies and skeletons, could further enhance the character design.

When creating background layers, for example, they must be made on a larger canvas. This one is 256 px tall to fill the whole screen appropriately.
