Glad you liked it!
You made a great point, I didn't saw it coming. I mean, we had plans to make more rpg stuff, so you would "grind" in many easy battles to eventually face the big guys. But, due to time constrains, we focused on the music part (as this is a MUSIC game jam) and made sure the 3 available battles would be greatly implemented.
I think the game will stand out very much when the RPG part is more complete, stay tuned, and thanks for the feedback!
