Cato is doing graphics and coding. It is an enormous amount of work. It took me 6 months of work, almost 2-3 hours a night at least 5-6 nights a week to finish 40k Multiset with graphics and coding. With the progress Cato has showed me so far, he has done a lot. The issue is he doesn't visit these forums that much. He is on Discord though. His info is in the first post.
