I tested Opus 5.5 and had it build an arcade game in Unity using the CLI and Claude Code.

The game is called Heatwave and is a quick and fun little police chase game.

Of all the games I've made, this is actually the one I enjoy to test the most.

I'm terrible at it, but it's fun.

Wanting another run even when you are bad at it is a pretty good sign. What took more iteration in Heatwave, the driving feel or the police chase behavior?

My kids loves Block Blast, so I decided to try making my own version for them.

It's not perfect but it was a fun experiment. My kids weren't impressed. Tough crowd.

Kids are the harshest QA you can hand a puzzle game to, and they reject on feel long before they reject on difficulty. Most homemade Block Blast clones get the rules right and still feel wrong, because the piece follows the finger instead of the grid and the snap lands late....
