Bugged as in it replayed the music track after the second round (which kinda doubled/echoed the music) then when it booted me back to the title screen it played the music once again without stopping the previous 2, which was a little cacophonous (once again, not a big issue given you can just restart the game entirely at that point)
As for the health bar, I thought it was a cool idea! I just also think the health on both sides should have been a bit lower to make things snappier. If it means anything, the health was so large I think I actually had mint top out at some point which did a lot of damage(?) but also cleared the tower she was stuck on, so the amount of health made things longer in that case
