Andrés, Go is one of my favorite games, so I'm excited to see that someone has picked up development again! It requires such balance between aggressiveness and defense, as well as local play vs spreading out on the board - I think it's a great game for kids to learn. I look forward to trying out

Do we have the ability to pulse width modulate the backlight LEDs? What is the resolution on the PWM? It's hard to know if this is feasible without a hardware schematic and specs on the backlight driver. The CL1 spec mentions a PWM signal, but maybe it only has four bits of resolution? In the
