I absolutely love the Inscryption vibe. Everything fits together really well and feels pretty polished in general. The theme of the jam is also very well built into the game. The uncovering of card's effects and level up mechanic was really cool too, there's a lot to explore.
I kinda agree with other people saying a tutorial would maybe ruin some of the vibe, but I think at least the core mechanic should be explained a little. I wasn't sure at what point my purity would destroy me if it got too high, and at the same time I didn't know for how much purity I'd have to aim for in the next fight. This kinda led to me try harding having purity on the border of turning red, and still getting defeated in the fight. I think this had something to do with fighting against your previous runs, if I've noticed that correctly? But I think just knowing the next fight starting power of the enemy when preparing for the fight would be really helpful without taking too much away from the mystery atmosphere.
That being said, it's definitely one of the best games of this jam I've played so far. Really well done!
