Nicely played! There were some lucky moments that could have gone either way but you made use of what you had.

Is “up” in between left and right, or is it the thumb button? Do people have different preferences with that?

Looks great! I built a controller recently too, just wanted to mention that I used the open source GP2040-CE on a Raspberry Pi Pico and it works great, it involved a bit of soldering wires with different connectors together, but there are now custom RP2040 controller boards that can run it and are plug-and-play.

I tried to play Ultra Sun using only my starter Rowlet, and had to put it down when the game forced me into a double battle. I would have been okay with hatching a second Rowlet from an egg but it didn’t work.
