Out of sheer curiosity, what board & pieces did you use to prototype this? I have a suspicion…
I'm pretty sure this one wasn't prototyped on boards/pieces from existing games but rather using a crude handmade board & some random pieces I had bought from spielematerial.de or elsewhere. It came to existence around the same time as Kurote and I think I used the same components for both? Hard to be sure though, it's been over a year.
