Cool, I might think about buying it

You may want to try it first. Apparently it is F2P with one constant, and one changing character. Or you can purchase a version with almost all the characters.

I'm probably going to try that F2P first.

Can't you buy a complete version though? That eliminates the F2P aspect of it.
