Slay the Spire 2 "may not be perfectly balanced yet," Half-Life writer and Valve veteran Erik Wolpaw says, but with 1,500 hours in the first game he has no doubt Mega Crit will pull it off

A worm eats another Slay the Spire 2 character in a sandy desert.

Erik Wolpaw – best known for writing Psychonauts, Half-Life 2's episodes, and the Portal games – has revealed Slay the Spire is one of his favorite games of all time.

Speaking to PC Gamer, Wolpaw reveals that as of late, he is currently playing, exclusively, Slay the Spire 2. "I'm either playing it solo … or playing it co-op with my son," he says. Obviously, the big chat around the game right now is how Slay the Spire 2 plummeted to 66% positive lifetime Steam reviews after its first major update earlier this month, but Wolpaw hasn't been too bothered about balance right now.
