I saw this on stream but I had to play it for my self for a fair review.
Overall: It's a fun game, I think, and the parallels between Harold and Goku get stronger every year. This game just makes that even stronger... like both Harold and Goku.
Game play: The fighting was formulaic, which I kind of liked because it was simple, but it lasted a little too long. Either shorter battles or more interesting action would have been fine. I don't think fire was needed with spark, but it did add some variety.
Music: It was OK.
Story: I've definitely heard the story somewhere before ... It is a fun retelling.
Graphics: They were fine.
Comedy: As an homage to DBZ it was fun and humorous. I liked the cal out to the foolishness of letting evildoers live at the end.
As a fan of DBZ I liked this game for what it was. As a Harold fan I am also liked this game for the comparisons I've also drawn between the two heroes. A good few minutes that I enjoyed.
