UFO 50 is fantastic.
Got a favourite yet? A friend and I have been paying a lot of lord’s of disconia and party house most recently.
For anyone not familiar, UFO 50 is an anthology of 50 games in the style of nes/SNES era. It’s made by Derek Yu, who made Spelunky before it.
OpenSUSE Tumbleweed has great KDE implementation. Best I found and stuck to last time I hopped around.
Rolling release yet super stable. Great configuration tools.
