Hey there! I just casually raced this with a friend and by accident found a setup for a boss quick kill on stage 4-4. I played the game on Easy but I checked out the run in the boards and it seems he follows the same pattern, so it might be useful. Playstation version, as well.

I've noticed the game barely has any activity and sadly I'm not really planning on learning this game, but I figured it'd be good to document!
