Thank you for taking the time to play! Your deck persists if you win, and reverts back to the last persisted state if you die. I think some proper messaging and animations would help with clarity here.
I definitely think the game needs more balancing, but it will likely be focused at the card level. The decks you play against won’t be randomly generated in the future, but will instead be the decks that other players have built by playing the game themselves. Cards in your hand map 1:1 with a crypt. For this reason, I don’t think I intend to add anything that will pre-run the deck to ensure it is winnable. The balance between winning and losing against other players is important to the overall concept in my mind.
All that to say I agree in a single-player concept this is a problem but hopefully the multiplayer context will alleviate this.
Thank you again for leaving such thoughtful feedback!
