Hi, glad you enjoyed our game! Thank you for pointing that out to us. That's a simple debug flag that we forgot to uncheck, but we appreciate your suggestion! Our plans are to eventually extend the game to have many more levels and add increasingly complex combinations of mechanics. While a booster pack was not initially in our design, we do like your idea of using it in a limited capacity.
Music is on its way as well! Thank you also for taking the time to comment, I know most people are pretty busy. We'll keep posting updates, so keep your eyes on the devlogs. Thanks again for playing, and we'd love to hear any future feedback that you may have.
