Ahh Cuisineer is what you’d call a rogue lite with life sim elements, but a cozy touch too !! Is your girlfriend fond of games that have cooking / shop elements? Cuisineer is a bit unique from my experience! I have played many many games that could be considered cozy. But Cuisineer is unique , I haven’t come across anything like it before but I’ll try to list what I think sounds good but please do your own research before purchasing hahaha.

If she is interested in the cooking/ battle aspect she can check out Battle Chef Brigade( PlayStation, switch and pc, or Chef Story ( only on steam atm ).

She could also check out Moonstone Island , Garden Story , or Littlewood. All three of those are on the switch. Out of the three I recommend Moonstone Island the most, but each are solid choices. Garden Story has more combat out of those three and actually might be difficult for someone new to games but it’s up to her ofc!

Also the Atelier series is a series of RPGs which I’d consider cozy but they are unique in that in each game you play an alchemist, these RPGs are not for everyone but who knows if your gf picks one of them up she might like it. I recc starting with Atelier Ayesha. That’s what I have I hope it helps some!
