Thank you for the feedback! I hope you enjoyed the game~
I never considered my game to be resource management, but the moment I read that, it clicked. Everything in the game is a resource, even time - which is really just a trade off for getting bonuses, in exchange for the boss getting stronger.
Game balance is definitely a concern for me. I don't think that taking too long would make the game impossible to win, but it does make it harder. The cards I think holds the most importance, so RNG is definitely still the biggest factor.
I'm looking into some way to implement logic that will favor the player more when they're suffering from bad RNG.
