love the style. i'm usually not a big fan op pixel-art, but this is really well done. great soundtrack as well. Also a big fan of the subtle "tutorial" at the start
i understand a lot of time went into developing the content, but just a little more love for the UI would have made a big difference. The font really clashes with the rest of the content, which is too bad, because it's an easy fix.
Great effort though! Keep it up.
