I don't often do gamejamming, but today I wanted see see how well my game-engine's integration with code agent tools work. It's very hard on touch screen, but try to beat my 2:32 record: collectingsmiles.com/temp/cr…

I bet there's a strong overlap between people who: • Turn on "Charge to 80%" the day they get a new phone • Beat the final boss with a full inventory of consumables • Take climate change seriously

8 months using code agents: - I ignore most of the fancy harnesses, while trusting the agents more and more. - Scope creep is dangerous. Almost anything feels within reach, but everything costs time. - I think I was a better programmer than Opus 4.8. Opus 5.0 is better than me.

Don't fear making a 2 week game. Those 8 months will be the most fulfilling 2 years of your life!

5 months using code agents: - The early frustration is gone. - I now intuitively where Claude will do well, and what to do myself. - Some days I don't use it at all. Others, I run 3 concurrent sessions. - Full automation is the now the frontier. Still discovering the ceiling.

Result of 3 months using code agents: - Went over the "hump" a few weeks ago - Starting to see accelerating returns - This thanks to session setup docs containing the "right" info - And developing good intuition of what's easy/hard for agents Probably at 2-3x efficiency now.

testing mirrors in project genie, they definitely don't work correctly, but the results are funny

AirDraw on Apple Vision Pro is incredible when you toggle on physics. Being able to interact with your 3D drawings makes them feel like they are actually in your room.

Result of 2 months using code agents: - Marginally more code produced - More advanced solutions feel within scope - Overall progress 50% slower, because I choose to go for those solutions. Will likely pay off? - I miss coding “in the zone” But I think I'm getting better...

Hollow Knight: Silksong, 60h Fatigue prevented 100%-ing, but still happy to have experienced this incredible game. It proved me wrong on boss fights – In Silksong I love them. Like in the best action animes, you enter a state of dance-like flow. Magnificent use of mastery.

Clair Obscur: Expedition 33, 13h Wanted this one posted ahead of TGA. Really wonderful game – looks/sounds amazing and a fantastic take on the classic turn-based JRPG combat (normally not a fan). Very very good. My only complaint was some awkward dialog.
