Best on a computer

Every pixel of the cave is simulated: wood burns, water douses fire and turns to steam, acid eats stone, lava meeting water becomes rock, and ceilings you undercut come down. You play an alchemist with a wand, making your way down through five depths, from a collapsed mine to a foundry and the Cinderdeep itself, with the vault at the bottom as the goal. Its twenty spells are real matter rather than effects: you can pour a jet of water, or spray oil and set it alight. Players have compared it to Noita, and the creator agrees that Fable took that game as its inspiration.

How the creator made it

Nil Ni says the game was built entirely by Claude Fable 5.2, and shared their whole prompt history, shown below: six messages. They didn’t name a genre: they say Fable decided to make a game like Noita. It was published on AIGameShare.

Code
The creator says it was “Built entirely by Fable 5.2”. Their prompt history, shown below, asks for “a stunning game” and a plan first, then a new, better version, and later says “The graphics look bad.” ↗ ↗
Cost
In the creator’s words, “it only spent 7 % of my usage”. ↗

From their post on X ↗ and 2 other posts on X (1 ↗ 2 ↗).

The prompt

- (11-09 22:41) “Hi Fable 5.2, show me your muscle. Make a stunning game, upload it to AIGameShare, and blow all humans’ minds. Make a plan first. Go!”
- (22:44) “Start building. Use the best design and the best tech. Go!”
- (23:20) “I think you can do it. A game in the same genre can have a new version. I want to see how much better you can do than the previous one. Don’t touch the old game. I want to see your new version. I want to see Fable 5.2’s level and be amazed. Thanks.”
- (11-10 00:25) “The graphics look bad.”
- (00:31) “By the way, I think it feels too polished now.”
- (00:41) “Can you make me a launch video? Keep it simple: a really cool expert player playing straight through from start to finish, as a screen recording.”
