I don't mind as long as they don't make some spinoff puzzle game like Encore of the Night. I also think a classicvania would work better for a mobile game, but at the same time every mobile game needs longevity with simple pick up and play mechanics. Something simple with RPG elements sounds OK. There was that mobile game Castle of Shadows, a CV rip off, which is really good.
I'd appreciate if they made a downloadable title for PC and Consol, but with Bloodstained on everyone's mind I think they'd need to do something to differentiate themselves, like a classicvania. How about an open world game like Simons Quest, which won't be too ambitious to make today.
