Did you know Sticker Mule offers printing (on) rigid yard signs? I've decided to check how #js13k 2025 design would look like on one and it turned out great!

js13kGames 2025 rigid yard sign

Yes, you read that right: I wanted to try Sticker Mule's new rigid yard sign offer and they delivered - I'm now a proud owner of the js13kGames-branded sign without even having a yard!

My browser-based VR game INSIDE CAT won 3rd place in #js13k... in the VR category. There were only 13 entrants in that category, but I'll take the bronze happily. My game fell apart near the end, and I almost didn't bother submitting it.

Thanks @end3r.bsky.social!

LittleJS rendering system is crazy fast. For the procedural hills in my #js13k game, I just draw a few thousand thin vertical strips. No sweat. 💪🚂
