Thank you for your review! Appreciate! And completely agreed with you about the dislikes. The music wasn't my first composition. I ended "writing" it at 4am local time, just 3 hours after the jam ended. Try to compose a more professional piece before: picked my guitar, but had completely lack of inspiration, and my music theory is at a beginner's level LOL About the mechanics, I run out of time for the upgrade system and the increase difficult curve.
But if you like to see more, please come back at the end of the review period for a major update, with lots of cool new stuffs (most from the "ToDo" list during the jam, and other that come to my mind recently)
Thanks again!
