Really cool concept and a fun interpretation of the theme! The screen size was too small which made it difficult to read some of the text which in turn made it difficult to play the game. I also wasn't quite sure what I was supposed to do at first, but once I figured it out I enjoyed the concept. It could have used more interactivity with the treasures (I wasn't sure if I had to pick them up myself or if they were automatically gained, and if so why they remained on the screen).
With some polish on the clarity, the concept could be made into a really fun experience!
