It looks pretty cool, but why is it missing a numpad? That’s kind of a big deal, even for people who just want to play games.
E. g. Caves of Qud is designed to move with num keys. And playing a fighting game on keyboard is way better with them too.
It’s fairly common for mechanical keyboards to come in different, smaller formats. Personally I prefer it for general usability—my 60% keyboard has no F keys or arrows or a numpad and everything can be accessed without moving my hands—but there is the odd use case that gets affected. People just have to decide how important they find it to have those keys available without holding down another key.
Do you use exclusively the backspace key when attempting to correct a mistake? I use the arrow keys a ton for moving through text fields. Most small keyboards have function keys to hit arrows, but I hit the arrow keys a lot. Seems like critical feature missing. I’m also a big user of page up/down/home/end. I can’t see giving all that up.
