big, free update to this space-y template!

hello to anyone who's been following this little template project! if you've been hopeful that more content would come this way soon, then wait no longer! here's a full list of all the updates to this new version on the template:

- the template project is now FREE to download (though donations are still much appreciated). I want this to be available to as many Game Boy devs as possible, so I hope it helps!

- deprecated options menu and replaced with a mute music option in the title menu

- split the game modes into 3, with only the original Classic Mode remaining the same.

    > Modern Mode is now extra-linear, with no power-ups or additional stages

    > Story Mode is a new mode that takes the original Modern Mode and expands on it.

        = no point rewards in this mode

        = multiple stages, including an optional area with a completely different game type (first-person gallery shooter)

        = new power-ups such as a bomb, invincibility, and extra speed

        = small bits of story dialogue to help flesh out a narrative

        = updated boss sprite and patterns, plus a new enemy type

        = 2 difficulty modes that affect access to map areas, on top of enemy spawn and attack patterns

- Super Game Boy compatibility has been activated, which allows for swappable color palettes in different scenes, which is on display in the new version. if you'd prefer the original DMG style, simply uncheck the SGB option in the GB Studio settings~

I think that's everything?? if not, I hope all the rest of what I forgot is still appreciated. if you have any questions, feedback, or suggestions, please let me know! and thanks for checking out this template~
