I love the inspiration behind the set, and the execution of the design is spot on.
I even appreciate that it's a completely dissimilar profile than the original C64 keycaps.
What I don't understand is the kitting. I'm not familiar with how CRP MOQ works so I can't really give any suggestions as to how to improve it without understanding the goal, myself.
2 sets of Alphas separate from a TKL kit seems fine I suppose. It's a good way to cover a popular format.
The Modifiers + TKL kit together is where I get confused. It seems like there's a ton of overlap and you're going to double up on a lot of keys just to get support for a 65% or non-standard 60% / HHKB / Tsangan layout. Meanwhile, there's an entirely separate kit of MAC mods?
Again I don't know anything about CRP MOQ so I don't really know how to better kit this offhand especially since I don't know how you are trying to achieve this or what the limitations are, so sorry I can't be more helpful at the moment.
Also, no 40's it makes me sad, but I'm glad to see a 2u and 1.75u in the modifiers kit at least.
