Finnish developer 10tons got in touch this morning to let us know that newly-released iOS puzzler Swingworm has been discounted from $2.99 to $0.99 today. The sale is “limited,” so get on it. It’s a simple thing where you drag the head and tail of a worm around levels to grab fruit. In addition, griddy puzzle game Azkend is free for iPhone right now. Grab this quick. I played the sequel in Tampere in Finland last week, and could hardly put it down. Do it: the lack of cost won’t last for long.
