I greatly appreciate the feed back. I will definitely keep you what stated about "X" and "Z" in mind. Pico-8 only gives you five buttons to work with, but I do see that within Pico-8, for "X" and "Z", I could have used "C" and "V" or "N" and "M." Something I should have tested. Thank you for pointing that out and I'm glad you enjoyed the game!
