I played Matsuda's route first, are the rest more of that?

Basically got the bad end and got to the very end of the "good" end right as they're about to skip into the sunset but pretty much quit there out of frustration. Are the other routes more of the same or is there a value in seeing the other ones despite how frustrating it was to get to the point I got to? Also is there an actual good ending?

Mitsugi's route doesn't have any non-con , if that's what you're refering to. The true ending of the game which explains what's going on that island has both non-con and gore , though.
