This is one of those simple games that I cannot stop playing. It's just the right level of difficult: It may take a few tries to beat a level, but I'm not ripping my hair out with frustration. I'm also willing to replay levels immediately after completing them in order to get a better score because I feel capable of achieving the goal times; they aren't unrealistic amounts.
The art style is simple and cute. It reminds me of pokemon and others bits of my childhood. When I'm not trying to cut down on my time, I like messing with the environment, mostly destroying dandelions. I feel like there should be an achievement for destroying x amount of dandelions. The first time I died, I laughed at the explosion animation; it was perfect. I also enjoy the sound effects.
Overall, this a a perfect not-too-hard, not-too-easy game. I can keep track of time with the "shadow" of my previous play. The countdown doesn't start until I press a key, so I have time to strategize. I highly recommend this game.
