This game is meant for who it's meant for. Mechanically it's almost flawless, and it has a charming little story with funny writing. I have two main complaints. The first is that the bonus missions don't let you use your own equipment from the campaign, and I really wish they would. If I wanted a challenge run I would go to the challenge run menu. But that is a nitpick, you don't have to do the bonus missions, and maybe I'm just being a scrub, I don't know.

My real gripe is that, while the game auto-cleaning pieces after you get most of the dirt is a very welcome feature, sometimes it was a bit finicky. Most of the time it was perfectly balanced. Sometimes it would delete whole sections of dirt because it registered as being clean too quickly. More often, and more frustratingly, it would require extraordinary exactness in the cleaning long after it was hard to find any extra dirt no matter how many times you tap that tab button.

It never got frustrating, though. It's a very well made game overall, and one I'm glad I played.
