Yeah a chart would be helpful! Although, again, I don't think it matters too much that the plot of the story is hard to follow, the characters and interactions between them were more than enough to carry the story. I'll play Vanlen X.5 next, downloading it now...
The minigames actually weren't too bad, it was just the rhythm one which was, and it was just because of the timing of the note hitting was off. Also, maybe the fishing minigame needed a tutorial... Otherwise, no real problems.
