Love the artwork!
This game has really beautiful graphics, you're an awesome artist! I've also seen (on your deviantart account) the enemies and other stuff you've drawn already for the upcoming sequel, and can't wait it to be finished.
All things I'd mention at this place that could be added, you've already stated you'll add for the sequel (for example leveling up), so there's nothing left to say for me except "well done. awesome!"
