ah man, that sucks...

Have you ever thought of having someone else fix the bugs (and split sales), or releasing it early access?

Looks good, but I kind of have a feeling of what this is worth, and I dont have such money
Contact conitec, maybe they are interested in using/adding this for new people to learn from (or parts of), alongside integration in the engine (Shade-C Evo)?

Good luck with the sale!
