I dunno about the choice of letting the right side be a mirror of the left. Intuitively, I think making the left side be a mirror of the right feels better. But to each their own.

We tried this design from the start and even made a prototype, but its typing feel is far too different from regular

The board looks interesting. However, I have to point out this is a poorly written IC. It provides virtually no info (not even the mounting style, really?) and does not seem to want to collect feedback. Perhaps you should rethink the purpose of this post.

Sorry for my oversight—some details are still pending confirmation. The drawings clearly shows the TOP mounting. As our size is relatively small, the questionnaire yields little useful data; major decisions will rely on our studio’s experience instead.

The following are yet to be confirmed：
Layout:  60%  Full-symmetry Alice
​Connectivity: wired
​Mounting:Isolated Top
​Typing angle: 11°
​Front height: 14.7–20.1mm (excluding feet)
​Weight: ≈1.5kg (All aluminum)
​Top Case Material: aluminum
Mid & weight materials: Aluminum / Copper/ brass / PC
Manufacturer: Hongtu

Unfortunately this set didn't reach MOQs. 

The casing near the thumb zone hinge split open, but the keyboard works totally fine.
