The visuals are absolutely soothing! The level design is quite clever too； sometimes you really have to rack your brains to get past a level. It’s a great way to unwind when you’re bored—just pop it open and play a few levels. The only downside is that 60 levels just isn’t enough； it’s simply not enough to keep you entertained! It’s a light-hearted little game—simple to play but surprisingly addictive. Just swipe your finger across the screen to bring colour back to the world； watching the grey， dull map gradually brighten up gives you a real sense of achievement. Perfect for killing time—I highly recommend it!
