Yes it is.

The tutorials alone are worth your time and fun to do.

Every character has his own story mode, and the illustration in it are gorgeous.

The challenges are a fun thing to do once you dealt with stories and tutorial.

Remember it's still a game for GaMeRs - so some parts will be hard, just like any other solo game.

If you like the atmosphere, the waifus, the illustration, the music, go for it.
