Chaste Puyo 20 Chain

I had previously made this same game in Raylib, however this new version was made using SDL. More importantly, I wrote a better function to handle the Puyo falling to look more realistic. Also this version has fullscreen support.
What it doesn't have is the music I used for the Raylib version. I didn't feel like adding in the SDL_Mixer library at this time because part of the point of writing it in SDL is to be simple, small, and fast.
Music can be added later if the game generates enough interest.
If you like Puyo Puyo, you might like this one because it is the same except now there are 6 colors!
