Updating the Map Selection Screen for #AvanteAtlantis
Still gonna update the Map Preview, to use the same assets as the original maps, so it's more easy to know what is happening

sidenote that if I had played Öoo (store.steampowered.com/app/2721890/...) before I wrote my IGF thread it absolutely would have been on it. genuinely one of the best platformers I've played. 3 hours of all killer no filler and does more with two buttons than most games do with a full controller
Öoo on Steam
A Bomb Caterpillar's Big Adventure! "Öoo" is a charming yet mysterious exploration puzzle platformer where you discover creative ways to use bombs!

Pixar designed Toy Story to be printed on physical film. The Disney renaissance movies were the same.
Today, it's hard to see them as they were meant to be seen. The versions on streaming and home media aren't quite the same films that ruled the '90s:

Yesterday at TPAC I publicized my draft proposal for adding a declarative templating API to the DOM.
github.com/justinfagnan...
The repo has:
📖 Explainers for the templating API and DOM scheduler API
🏗️ Full prototype implementations
⚗️ a JSX transform
⚛️ a mini React-like framework

i think my fav moment i've ever experienced in a game is taking a few steps out of the starter town in morrowind when a body fell out of the sky & thudded at my feet
looted his corpse to find a letter gloating about his leaping spell creation & how he was going to have the last laugh
such whimsy 😌

i just started Tower Dungeon. the stonework in this is fascinating. it feels as though the stone built the landscape, the humans and other creatures are a secondary ecology. it has the spirit of Blame!, but the lens here renders it as much more surreal.

when you know exactly how many Things you're missing, or even have a vague checkmark to tell you you're "done" somewhere, it sucks the life out of a space. Giving players permission to be Done with something deadens it in their mind, it's what turns worlds into theme parks

Alright progress. I imagine most won't understand what you are seeing. I had a crazy idea a week ago that all the ideas we have about async could be wrapped into the native behavior of a runtime reactive system. So I dropped what I was doing to test.

New take on the tunnel gun:
Make a tunnel, walk through it, and then close it up behind you.
Going to experiment with this for gameplay in a mining context.
