This is really helpful, thanks! I couldn't figure out how to combine exclusions, or use non-tag exclusions, for example a single filter for:
> not tagged pixel-art and not tagged visual-novel and not action genre and not platformer genre
It also occurred to me that OR might be better (quicker?) in some cases:
> genre adventure or genre role-playing
...I'm not sure if building a whole query language is in-scope though :)
