Here is my in-game profiler.
It's very useful to quickly find and fix inefficiencies. I recently implemented zoom to cursor, and it's a joy to use now. Another handy feature is CTRL-click on a profiler marker to jump to the code location.

Do you already have a present 🧑🎄? It is only a little more than a month away!
In other news, I managed to get tracks in the snow working 🥳
It just broke a few other systems, but I guess I can fix those 😅
I'm really happy how this is starting to look!

Just released bc_crunch: a tiny (~700 LOC), C99 library for lossless BC1/BC4/BC3/BC5 compression.
One .c/.h pair, no deps, no malloc
GPU-ready output
Zigzag + delta + popcount/dictionary tricks
Tested
Perfect for games, procedural assets, streaming textures.

🚨 "The Making of Double Fine's Keeper" is now available! 🚨
Many of you have been asking for this one; we're happy to say the cameras continued to roll here at the studio during Keeper's development. Come see how this very special game came to be, from the team themselves! 😊

If you are familiar with Reply All, but have no yet listened to @hyperfixedpod.bsky.social, listeners are saying the latest episode is a “banger”. You should maybe give it a shot.

Hey look, Israel broke the cease-fire, twice, in two different ways, within 24 hours - again.
NEW: Israel informed the UN it will permit only 300 aid trucks into Gaza daily, not the 600 mandated by the ceasefire it just signed.

A bit technical thread 🧵
I’ve been improving the in-game ambient occlusion system - and ended up with something I call:
Blob-based Analytical Ambient Occlusion on Primitives
Here’s what it does to the final image:

Very cool to see Eike's progress on his project, and the sheer speed at which he's working. Also I find impressive how the smooth web build is. Try it!
This is 8-bitBot: A programming puzzle game that I am working on and aiming to release in December.
There is much to do still, but it is coming nicely along so far.
Steam wishlisting: store.steampowered.com/app/3959370/...
Playable demo on my website (a bit outdated): quakatoo.com/projects/cod...
