I tried this with DOOM. Fable 5 did a pretty shit job. Astra made pretty crazy animated sprites and was pretty good considering.
The fact that these are at all playable and 100x my programming skill level is pretty depressing from a certain pov. The ThreeJS dude posted ab how demotivated he was to continue his work, and while I was never a dev that did much with webgl, I commiserate.
My hope is that this drives a new generation of hyper creative content from those who don't give up. I mean, of course it does pacman well. Pacman and its clones have been done to the death over decades. But what if we ask AI to write finnegan's wake 2?
I don't think it makes sense to have the prompt be that short. This is basically a bench.ark of how models interpret an overly vague prompt. It should at least be "Create a pacman clone in a single html page. Make it faithful to the original" if that's what we're scoring it on.
The game mechanics are shockingly hard for them to get right. You also reveal some of their personality traits. The GPT‑6 and Astra models tend to include a lot of cringe copy as well as their own personal graphics style.
Opus 5-5 seemed like a perfect clone, with others displaying flaws in an initial look. Astra notably created a bunch of surrounding ugly crap to look at.
Yes, Opus 5.5 is the first one that I don't have any notes on. It's just as impressive on other tasks I've given it over the last week. A clear step change.
I was just coming here to say this. I looked at all of them, and Opus 5.5 at high effort seems significantly better than every other clone.
Buffered controls, different pathfinding AI for each ghost, level transitions, etc.
Gpt-5.6 sol high technically completed the assignment as well, but the gaps within the pipes used to construct the maze, the lack of pause when eating a ghost, etc made it feel far less polished.
These results get better and better, but the half-baked pac mans games and pelicans are just funny.
You cannot prompt that level of brokenness. Same for those slop-posters you see everywhere.

It seems like a lot of the programming is cookie cutter type stuff (where these ai programs shine) and should be easier.
They can be amazing, but promoting “make a pac man game” seems like an exercise in which model has the best training code that was Pac-Man.
Remember when people considered you a genius for prompting with "You are a skilled writer....".

It has the advantage of taking good screenshots and letting me know if it’s decent within five seconds of playing.
