We just wrapped up the Global Game Jam! What began as a solo adventure became a fun remote collab with Vlad and Josh. We made a pixel-art platformer on a grid, where masks apply XOR patterns to the level—line or cluster—transforming the terrain.

After a long break I finally got my rig behaving again. Test target: M1 / the Crab Nebula — ~5h captured in H-alpha over two nights (clouds after midnight on night 2).

I wanted to test Unity’s URP and learn a few new things during last few days. It turned into an experiment where rooms can move when you’re not in them. A little bit like the Cube movie.

I resurrected another one of our game jam games. This time from Global Game Jam 2014. We had just started using Unity back then and didn't know much about best practices. The code was kind of hell, but the game almost worked on the newest Unity version anyway.

I’ve decided to revive some of our old game jam games and make web builds of them.
Here’s the first one from 2016 — OCDungeon. Crazy retro FPS with a twist.

Almost missed this Ludum Dare! Found out on Saturday morning. The theme was perfect, got an idea instantly. Started Sunday, finished Monday night with help from Josh & Vlad. They nailed the testing, balance, and SFX.

Working a bit on the UI for my small puzzle game. Wanted to try something more interesting this time, so I ended up with these flipping tiles. What do you think?

Made this small math puzzle game last week during Puzzle Game Jam. Unfortunately I didn’t manage to hit the deadline, but I will finish it anyway. Missing just some win animation, levels and menu :) #madewithunity #indiegame

When updating to Unity 6000.0.47f1 my fixed timestep got set to 0.0001. Most of the projects will loose tons of FPS so it's pretty easy to figure this out, but on small projects I see only tiny bit different physics behavior :) @unity.com
