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!

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!

I can relate to this! My #js13k game was rated poorly in part because the gameplay was slow and lengthy.

I always set out to make something "fun" that will "win"... and then settle on an overly complicated game that I (and only I) find interesting.

The main takeaway from #js13k 2025: don't sink time into big, complex, self-contained concepts you don't have resources to finish properly. Start small but complete - then polish it as far as you can.

Next year's goal: get the game to playtests and tune the gameplay from there 🚀

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!
