Lights hanging from ropes are cool, but I’m not sure they’ll have any use beyond the visuals. And that’s probably not ideal. Everything should have some purpose, right? :) #gamedev #unity

I spent the last three days creating this little game for the GMTK Game Jam. The theme was "Count Down." There are 19 levels, and you count down in each of them. You need a bit of knowledge and thinking, but also some arcade skills. It’s a mixture of everything 🙂

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). EdgeHD 14” • ASI6200 • Planewave L-350 • ScopeDome 3M

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. ▶️ Link in comments

My game The Collector, made for the Ludum Dare #58 Game Jam, ended up in 7th place in the Jam category. Huge thanks to Freeek and Lokiman, who helped a ton in the last few hours. ldjam.com/events/ludum...

🎙️Podcast #370: The Collector Nedalo mi to a probral jsem to se @split82.bsky.social. Je to sice pouhá gamejamovka, ale krásně na ní lze ilustrovat jeho iterační proces designování. Nasdílel mi i obrázky z průběhu vývoje. Vlevo první, vpravo finále. #modrakfriends modrak.podbean.com/e/370-the-co...

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. Play it here split82.itch.io/the-collector #indiedev #gamedev #ldjam

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?

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

Can someone recommend me a good alternative to Logitech MX Master 3S? I love the ergonomics, but hate the materials. No idea what they are making it from, but they somehow dissolve after quite short amount of time.
