It's nice, fun!

It's a pretty fun little loop =D

Loops smoothly, really well done

Though it doesn't sound much like a boss theme... But that depends on the game and on the boss, so, I can't complain =P

That explosion also sounded a bit too loud...

Also, the song is pretty short, and after one loop, it starts to get boring =/

Try to make it longer and vary more :D

Rock On!!
