Quoting: subCurrently I'm addicted to Cuphead.
And damn is it good!

Honestly, best game I played in a very long time.
Extremely challenging, but so well and lovely executed.
Yet so different. It's basically one boss fight after another.

Unfortunately it's Windows and Xbox-only thus far.
I saw reports running it successfully on Wine.
But I'm pragmatically use Windows in this case (yeah, not a Wine fan).

It's a Unity game and devs said they'll look into bringing it to Mac and Linux.
Their exclusivity contracts only cover consoles.

So watch out should it be released on Linux.
