This is such a fun homage to classic games and a great start to a much larger game! Definitely take a look at the balancing of your classes (sorcerer had much higher strength than magic, for example) and -- as others have mentioned -- consider turning down the frequency of the random encounters. Personally, I really enjoyed having the intro credits / cut scene while you're following Nadia back to her shop instead of just watching everyone walk with nothing else happening. But the coloring was a little hard to read.
Overall, excellent entry and I'm excited to see what you do with it! :)
