Thank you! Yeah, third level is meant to test that you have really play attention, you know at least how to cycle cards, and time correctly. It's a gate before everything else and see if you have learned correctly. Worst case scenario is pressing R... (I forgot to add in a check where if all of the cards are unplayable it should start the lose condition).
The concept and game loop was something I had to think thoroughly so it was nice to see it pay off!
In any case, thank you for playing!
