Good God, not another Zelda parody...
There have already been a ton of Zelda parodies. NewGrounds needs something different. If you are going to do a Zelda series, do it DIFFERENT... something UNEXPECTED, something AVANT-GARDE even. Don't do what everybody else does and just change the plot.
Besides that, everything looked okay. BTW, a 5 on the score is an "OK" by my standards. It's nothing special, but nothing immensely sucky either.
