Thank you very much for the update. The new AI is challenging, and also really funny.
Here are a few simple suggestions that I think would be clear improvements:
1. Have metal textures and SDR alternates off by default. Oh, and rainbow FD off by default and bright transition disabled by default would be great too, but maybe that's just me.
2. Bring back a way to enter Melee with one player only. (Maybe hold start for 1 second?)
3. In Debug Menu > Extras > Live Analog Input Viewer, the right half of the screen is currently blank. Could you maybe include the feeds for controllers 3 and 4 there? That would be very neat.
4. Having the good old develop camera control back in some form, preferably with a toggle (menu would be better than in-game button combination, since there are so many of those already) or with using the currently unused develop modes (debug or debug-develop, which are currently labeled as "do not use" 2 and 3 if I am not mistaken), so that develop will function like it does currently, but debug-develop gives back develop camera control, for example.
