Good concept. Needs some work
While the gameplay itself is easy to progressively harder, there are a few things i did not like.
Normally i get paid for this sort of analysis, but here are a few observations and suggestions:
The tiles are too tiny
Story progress: took me a while to find the "next" arrow/button
Limited settings (only volume, it seems).
No home menu to find an exit link from the current game when desired
A quick voice sfx for the characters (basic, like in newer Zelda games) to give them a little life.
One thing I'd like to know is, what are the jewels collected for? Will they be used for purchasing new outfits, hints, backgrounds, tile designs, etc, or just as markers of the next puzzle?
Overall it's nice, but to me, it isn't engaging enough.
Keep up the good work.
