I played countless hours of Cave Noire this year. It’s a coffee break roguelite that released in 1991 on Gameboy.
I fuck around with old games a lot but there are not that many games I get really into these days. Cave Noire is similar to Desktop Dungeons where every attempt is a short puzzle so it fits pick up and play nature of Gameboy. Can’t recommend it enough if you’re into this kind of stuff.
How do you stand image scaling on 3DS? It’s either poststamp sized or horribly mangled by non-integer scaling on a very low res display. It’s the reason I keep DSi along NN3DS.
