If for some strange reason you don't have BeaverTap Games' Mikey Shorts [$1.99] yet, here's your chance. We reviewed it after it was released a little over a year ago and to this day still totally dig its speed run style gameplay that'll have you redoing levels over and over- Particularly if you're the kind of person who takes pride in dominating leaderboards.
Additionally, the sequel, Mikey Hooks [$1.99] is also on sale for 99¢ down from its regular $1.99. Hooks takes the similar Mikey gameplay but as the title suggests, adds a grappling hook mechanic to spice things up a bit. Both are great games that everyone should have on their iPhone.
I'd give Mikey Shorts a try now that it's free, and if you even vaguely enjoy it, definitely pick up Mikey Hooks. You really can't go wrong with both.
