La-Mulana

[Dunkelschwamm]

It's to simulate the limitations of the retro games where only a certain amount of colors could be included in a sprite's palette. With more colors they have to trade off their transparency color, so you get black blocks around the sprite, though usually it isn't all that noticeable against the backgrounds. Since in La-Mulana it's a specific part of the sprite, I didn't remove it.
