So a few titles have dropped in price from a few bucks to absolutely zero. They are not the best titles but they are fun way to spend a few hours. I don't know how long the deal is for but check these out:
Operation Wow HD: $1.99-free
This is a basic port of a click and shoot game. You have various cute animals armed to the teeth to blow away with either bullets or grenades. Yep, its that simple.Graphics are cartoon and cute and the game continues to scroll which gives it some speed while playing.
Ozone HD: $4.99-free
This sizable game puts you in the shoes of a ball that moves around the level collecting yellow orbs while avoiding traps and escaping the level. There are 50 levels and the previous reviews for this title were decent and its worth the space on your iPad for a play-through.
