Besides from the girl's speed, not being able to move diagonally and how tricky the 6th star attack can get, it was nice to play. What I'd consider the main flaw, was getting stuck at some points of the game, but I managed to reach the credits myself, phew.
For the same reasons, I don't know if I should recommend it or not, because it IS enjoyable and worth playing.
I like that nostalgic monochrome style and of course, the dialogues from the announcer. I've got plenty of screenshots of wacky moments of this game.
It was a good idea to dig on old games in this site.
