Hey, Battletoads music! :o
It’s a bit too low tempo IMO for an RPG battle theme and probably doesn’t fit very well for something like this, but, hey, that’s just my two cents.
I’d take it that this is your first game, right? Do note that using more familiarized music from more well-known commercialized games, such as the Battletoads song here, will probably have some players frown upon on you a little for doing so, like Indra (she hates when people do stuff like this). I don’t have a much of a problem about it if it’s your first game or that particular song being used isn’t very well-known or utilized as much, but try to avoid using songs like that as best as you can and find something that's a little bit more unique to the situation if you really want your game to stand out more from the crowd. :)
