So I tried the realm mode thing for the first time. Party on whatever it is below highest difficulty, basically got my face knocked in repeatedly for a bit.
Said, okay. This isn't working, let's try solo. Knock the difficulty down a notch, it'd be reasonable for solo run to be harder, right?
... Kudo just goes, "I'm not here to be reasonable, my friend, I am here to
fuck."
Straight crushes his way through everything in his path, only once goes down to half health (that, for all of one turn, by that point he had like 30-40 hp worth of healing in his deck). Clean sweep wrecked the whole run, apparently put me sixth (fourth, if you don't count endless runs) on the weekly leaderboard for solo hard mode.
Turns out, solo is probably easier than a party is, and it's a pretty nice experience

Gordian Quest, a deckbuilder that's basically D&D meets Slay the Spire. Has some pretty interesting things going on, including throwing bears at the forces of evil.
