Slay the Spire is an excellent game and this is a good price for it. But I would recommend trying to get it on pc if possible. The mobile port has some annoying bugs like crashing after rotating the screen and playing startup music even when muted. Also, I ran into an issue where most of my progress and unlocks were reset randomly, despite keeping the in-game achievements and run history that showed I had already had access to things. Support for the mobile game goes through Humble Games, and they just said it was a known bug that had no fix scheduled and offered me a refund. I have had no issue with the pc version in Steam however. Could be good on a deck I’m sure.
