Hi! Thanks so much – that certainly sounds a whole lot like a typo, because having the search decks face up is a terrible game mechanic! I'm very sorry, and thank you for pointing it out, I'll make sure to correct that.
I love your idea about an alternative mechanic to use instead of a tower – I'm really busy this week but I'll try to test that out as soon as I get the chance. I think it's a great idea to make the game more accessible to people who don't have a Jenga-game, or have a cat (!) or have trouble drawing from a tower for various reasons.
Many thanks!
