Played the game, didn't complete it, though, got to second world, the level where you have to deal with two red toads, then I had to restart the browser for an update, and when I came back, it turns out, that the game doesn't save. I think that for a long game like this, this should be a high-priority feature, cause most players won't complete the game in one sitting.
Other than that, it's an alright puzzle game, most of the mechanics I encountered so far were familiar to me.
The art looks amateurish, but charming.
And I'd say I was a bit put off by the morbid nature of the game, when you have to feed other fairies to toads.
