I have played the first and second one from this franchise and they surely are tough games but... this game takes it to next level. This is by far hardest puzzle game what i have ever played and you will see why when you put the game on. Struggles surely start when you get near the end and it is not coming soon as this game is really long.
Your goal in this game is to solve puzzles. Make Lolo to catch all hearts in the stage, go to the opened chest and run to the exit. There's lots of different type of enemies ahead what will cause more headache to you in this game.
If you really enjoy hard brain teasers. This is surely your thing.
