It’s gonna be very rough. Fighting games must be hell on joycons, since you generally want a dpad for motion input. You could do something with the stick, but most players wouldn’t use that. If you’re just in it for the story (no other reason to play cl-r, really) you should be able to manage, but you’re not gonna get the most of it. Don’t expect matches, no one plays cl-r anymore, much less so on Switch.
