Really worth the time
Good music, nice art and animation, cool crossover, etc. blah blah.
In short: just awesome.
Although I miss an option to see the lyrics.
Oh, and the change of costumes with every playthrough is a funny gimmick.
Wait a sec... do I see a reference to "A Harry Potter Musical", that is, Rumbleroar in person and near Pigfarts? Hell yeah!
