Thank you for the comment! Your game idea sounds so fun and I am looking forward to hearing updates. These music packs are 100% free and I want you to feel completely uninhibited in using them! If you do find my music to be a good match for your game and feel like paying/donating, I would be more than happy to write some additional personalized music for you. Feel free to reach out any time to discuss details if you are interested in this at any point. In the meantime, best of luck to you in these early stages of development!
