Some tutorial boxes added guide players with the usage of the powerups

Pause menu added

"Pinch" mode added to the boss

New palettes for the levels (with the player's palettes adjusting to the mode of the level)

New stage layout recreated from scratch

New music added to Emerald Hill's, Wing Fortress, and Invincibility's themes

Lives system changed to be based off of rings

In Wing Fortress, if you go behind the start with the rocket boots and then keep going up, the level does a weird vertical wrap thing and then just drops you at the end, may wanna fix that.

Continue to develop the hack. The ideas are really good.

This was an incredibly fun hack to play. And that boss battle caught me off my gaurd. Excellent work!
