Would love to see more Karryn, and glad we have what we have. Gym side-job is just icing on the cake for me.
I believe the one thing some forget is the effort the art requires. Sachinima hand draws every subtle variation, on top of unique poses, even redrawing older CGs to bring their quality up-to-date. So many JRPG H-games talk about "200+ type CG variations", yet usually it's just a subtle clothing/facial expression/mess on a simple side-view CG.
While KP lacks variety for some people's taste, nothing but quality has been dumped into the poses/scenes that do exist.
Karryn is the best example of a game that looks like a quality single-frame CG from an Nukige NV, yet the scenes dynamically change on both player and enemy input.
TL;DR - "Would love more KP, and let's love what we have. Ren n' Sachi are quality peeps. Last thing we want is another project abandoned via burnout. While nothing major is planned for the future - I'm sure Gym won't be the end."
