I had a fun time playing this! I loved the names of the MaestroMon, the cities/towns, and the art style was very spot on with the Pokémon vibes. I love Banjowl so much. The music was phenomenal, Ampsterdam was definitely my favorite track. The musical theme is done very well and flows into the setting of the game very organically.
My only issue is that the combat gets repetitive towards the end, and it feels like some of the Maestromons you fight are a bit spongy. The QTEs are fun, but I feel they should have a shorter sequence, and then some variety would be nice as well. It also felt a bit grindy to level up your current Maestromons and was just better to get new ones. I am a big fan of elemental triangles, so the concept of Classical vs Rock vs Folk was very creative and unique. If you guys had more time, since there are so many different types of music genres, I could see there being an elemental chart similar to how Pokémon works.
Overall, great experience, great work, and I would love to see more of this! I also hope that Nintendo doesn't send you a cease and desist, lol!
