Really well done with the mechanic. The game also has a cute and consistent artwork. The last level was pretty fun to figure out. I appeared to be easy at first but the amount of ways we can solve it it was so fun. Out of the fifty-eight septillion one hundred forty-nine sextillion seven hundred thirty-seven quintillion three quadrillion forty trillion fifty-nine billion six hundred ninety million three hundred ninety thousand one hundred sixty-nine ways to arrange the tiles, only fifty eight thousand two hundred and sixty would be able to finish the level. Hence it's a hard level.
