Great concept and execution! What i liked most was how the theme, gameplay and art fit so well with each other and gave a tight well rounded experience! I loved the hand drawn map, symbols and tiny characters. The grid was also done very organically as part of a paper - looked great! Although all of the elements were hand drawn, it was very easy to distinguish each one and it did not interfere in the gameplay at all. One thing i would change is the image on the left which felt a bit inconsistent with the rest of the art and the UI slider for the speed.
The gameplay itself was engaging and i liked that you kept a star based system and not simply win/ lose. Overall great job, would love to see this as a full fledged game :)
