In context:
It’s difficult to review a game like this. It costs $12.95, and yet, it feels entirely worth it. There is nothing really wrong with it at all. It could be longer, and perhaps the introduction of hazards halfway through was not entirely necessary, but that’s about it. The controls work perfectly. There are secret flowers to find that will have you replaying the game at least a couple more times – though you’ll want to do that anyway. There’s trophy support, and they’re all rather mysteriously described, so there’s definitely enough content to keep you coming back. That’s about all I can say without spoiling the experience. It’s simple, it’s genius, and it’s great fun.
The difficulty is that there's not a huge lot to describe, and there's nothing really wrong with it.
It feels worth it because it's a great game. I actually think $12.95 is on the expensive side.
