I bought this as soon as I saw it was available in the US. After gaming since the 70s anything new and/or unique catches my eye and my $. This one is both. You light a "match" which is your cursor, and then try to catch as many other spots of light that fall from the top of the screen to keep your flame from burning out. But there are other things in the game that are after the falling light and your flame as well. Plants grow in tendrils and will grab the falling light before you can. They'll also grab you and put out your flame which ends the game. There are also falling dark leaves and rain drops that can extinguish your flame. As time goes by the vegetation will fill in the screen if you don't keep it at bay. You do this by burning the plants back. You can upgrade your flame as well as pick up other add-ons but there is no IAP that I've seen.
A great game with a slick presentation and a refreshing change of gameplay pace.
