The song is called "A Fierce Good Fight" and is borrowed from the game "Killer7."
A more subdued version is also used as the stage background music for the "Organ" area in the game, and is inspired by the image of a beating heart.
Thank you for playing!
I'm glad you liked it.
I never thought I'd suddenly break the sequence and get a Magmaul! (Although that's the route I expected, lol)
I think it would be a good idea to add button configuration options, so I'll implement them someday. (It won't be in the next version, though.)
The music in the Grove area makes me feel sleepy, so I'm thinking of changing it.
Thanks for letting me know the hidden Battle Hammer acquisition flag was incorrect! I'll fix it!
