Slay the Spire and Darkest Dungeon can be played with only a mouse and you don't need any reaction, maybe when you configure the overlay in the settings for the games it's then playable with only the keybord. Maybe you can also play Dredge in the passive mode with only one hand and only keybord I havent tried it out with this restriction

Yeah, thank you!

I will do, although I don't share or torrent and when, only with my friends who know that I pirate

How much corpse:earth ratio do you need to be it acceptable?
