I rarely write reviews, but...I LOVE your puzzles, Bart Bonte. Whenever I see your name, I flip! 😁 I discovered your puzzles when I was 8 years old when I played "sugar, sugar", "Factory Balls", and "40x Escape". I love how your puzzles are hard, but not frustrating and how every level is different. Is the next game in the series "green"? 😂 The only bad thing is that the game never lasts long enough! 😂

I finished blue and enjoyed it so much I had to play it again. There's an option to remove the game data and start all over. The levels are the perfect amount of difficulty and are fun to play as well. There's no ads unless you ask for a hint. There isn't even a pop-up asking for a rating and review. Bart really knows how to make a great gaming experience. Definitely recommend downloading the game. You won't be sorry. Also try red, yellow, and black. Black's music is my favorite so far. Ty Bart!

Another good puzzle by Bart, like previous games: yellow, black, and red, there are brand new levels (obviously). But after finishing the game, I feel like the levels are little more straightforward than require more thinking, which itself is not bad, but some level are quite easy to overcome, but still satisfying. Surprisingly, he still use the same song like the previous three which I thought he'll make a remix or something for this time but nothing to complain here. A good puzzle game :)
