If you love Angry Bird and Tiny Wings then you will love Temple Run, a free game app for Apple and Android that utilizes the touchscreen. Temple Run has been available for the apple market quite some time and has also been released on android. It was downloaded more than 1 million times in under 3 days when it was first released on android and is one of the top 50 most-downloaded apps (As of December 2011). Here's why...

~The Premise~
You're an explorer (Think Indiana Jones but not as Harrison Fordy) who has just stolen an idol from an ancient temple. Angry monkeys (Think Wizard of Oz monkeys on acid and marathon trained) begin chasing you. You then have to runaround a maze of ledges with various obstacles in your way to escape the evil monkey things.

~Controls~
The game is played entirely with the touchscreen and through tilting the device from side to side. You automatically run so you don't need a control for this but have to change directions, jump and slide in order to avoid death. You also have to tilt for side to side to order to gather coins. The controls are:

Slide left/right - Change direction
Slide up - Jump
Slide down - Slide underneath
Tilt left/right - Collect coins and run on thin ledges
(Trip - Not technically a control but can be used to advantage. trip is went you run into a low branch. At the beginning if you trip it allows the monkeys to get closer to you which is not good, two trips and you're out. However, when you've advanced a bit to the faster speed you can use a trip to slow you down but make sure you only trip once)

~Game play~
There is no finish line in the game, you keep running around as far as you can until you die. The path and obstacles are random (if you run in a square you never get back to the start) and there's good variation between cliffs and tracks, etc, there's always something new around the corner. Each time you die you get a little message on the screen relating to your method of death which I think are pretty funny. I've played the game on both the iphone 4s and an Archos 101 G9 and have never had a problem with game play. Graphics are quite good (is a 2d game) and looks great on a HD screen. You are also given specific objectives ('Objectives' on menu) based on score, number of coins collected and distance ran which increase your points multiplier as you achieve them and 'Stats' provide you with details for both a single run and lifetime play. The desire to beat your current score will keep you hooked. The music is also fun.

~Coins~
As you run around the game you can collect coins which can be used in order to unlock power-ups, utilities, new characters and wallpapers (See below for descriptions) from the 'Store', shown on the main menu. You can also buy additional coins with real money (Which keeps the app free i guess) but I've never done this. To buy more coins click on the 'More Coins' option on the main menu or 'Get More Coins' from in the store. You can buy coins in 2,500, 25,000, 75,000 and 200,000 quantities but i can't figure out how much this costs, there's nothing on google and the app fails when i click on them at the moment. You can play the game quite easily and unlock stuff without purchasing coins with real money though. You also get 250 joins for liking Temple Run on facebook and 250 coins for following it on Twitter.

~Un-lockable Powerups~
There are five powerups each with 5 different levels of upgrade, costing more the further you get into them. E.g. The first level of a powerup costs 250 coins, second level 1,000 coins, level three 2,500 coins and so on. Powerups are available randomly in the game after you buy the first level and you have to jump for them. The value of the powerup is dependent upon the level of upgrade you have.

Mega Coin - Worth a certain amount of coins
Coin Magnet - Automatically collects coins without tilting
Invisibility - Saves you having to jump
Boost - Increases speed
Double Value coins - Increases the value of a coin after a certain distance.

~Un-lockable Utilities~
Utilities are one off boosts that have a single cost each time.

Wings (500 coins) - Resurrect straight after death
Boost (2,500 coins) - Boost 1,000m at the start of the game.
Mega Boost (10,000 coins) - Boost 2,500m at the start of the game.

~Un-lockable characters~
Costing between 10,000 and 25,000 coins, new characters are exactly the same as the default dude in terms of game play, they just have different appearances.

Scarlett Fox, a female explorer
Barry Bones, a cop
Karma Lee, a Far East explorer
Montana Smith, a cowboy
Francisco Montoya, a conquistador
Zack Wonder, a football player

~Un-lockable Wallpapers~
Three wallpapers are available for 5,000 coins each. I have never unlocked any of these though so i'm not sure how good they are.
