Infinite Dreams's beautiful-looking tower defence title Jelly Defense is currently available from the App Store for a mere 99c - down from its usual price of $2.99.
Taking charge of the Jelly forces, you have to repel invading armies by strategically placing and upgrading towers.
Jelly Defense stands out in a crowded field partly because of the colour-coded towers which add an extra layer of strategic planning to proceedings.
And partly because it's absolutely lovely to look at.
Oh, and it doesn't play badly, either - we gave it a 4/5 in our review.
The game will likely revert to its full price sometime tomorrow, so if you're looking for some wibbly-wobbly strategy fun, then dash to the App Store and grab Jelly Defense for 99c.
Now.
