While the game isn't very mechanically complex and is relatively short compared to most mobile games, it's still very good! In a sea of quickly produced slop games it stands out as full of charm and personality. It's also fairly replayable and has a very reasonable amount of ads. Overall if you need something to do for a few hours while bored, this game is an excellent choice.

Support this game! $4 to remove all ads, not leaving a peep. Play with sound on, you'll be engrossed. Intuitive mechanics, so good for kids too I'm sure. This is one of the good few games on this platform that is unique, thoughtful, and not an ad farm.

Love the game! It's a great combination of laid-back and addictive. It's part puzzle game, in that you need to pick the right shape, time, and location to get the best reaction. When you hit a wall in progress, it allows you to upgrade what you began with, helping you to pass stages that were truly impossible to start. The initial minimal design gives way to a fireworks show of color and shapes as you progress, and the pace of that progress is tuned just right, IMO. Overall a great game!
