I'm glad you like it! I actually made an ssvep pong game a while back with this, was kinda hard to play as the paddle was really small but was a cool concept demonstration. I am working on a video for this device to show off its capabilities with more depth as the current video on the site is very old.

With regards to higher channel count, yes I was thinking about this however it will likely not be released for a few months or longer. The firmware/software rules change a lot when you start daisy chaining the ADC so dev time takes long and I need to reincorporate back into these software ecosystems. Hardware config is also a bit different.
