I like that the PLAY STORE video for The Room 4 seems to be a video showing how the PC version looks much better than the play store version
Not played them myself, but I heard that they work better on mobile due to the tactile nature of a touch screen. Not to mention being originally designed for mobile and all having 5 star ratings.
Might depend on the size and power of your particular mobile though.
I can’t imagine Castlevania working that well with touch controls.
