Very unique game, you have my highest points on innovation. This was very challenging for me as I was very lazy to count the tiles and memorize them. Perhaps you can add some extra spatial sound effects on the levels so it's not all about memorization, but really playing it by the ear.
With the aesthetics/graphics, I really liked what you've done here. I thought it was a bit of a shame that I couldn't look at it much while coursing through the levels. So I have this idea where the background goes black and the only thing we'll see is the cute character. We still can't see where to go, but at least we can see some of the action. 😄
Nonetheless, good job on making the game, definitely has potential!
