+Mr. Rescue
+==========
+
+Firefighting game made with LÖVE, developed by Tangram Games.
+
+About Mr. Rescue
+----------------
+
+Mr. Rescue is an arcade styled 2d action game centered around evacuating civilians from burning buildings.
+
+The game features fast paced fire extinguishing action, intense boss battles, a catchy soundtrack and lots of throwing people around in pseudo-randomly generated buildings.
+
+As of version 1.02 we have added XBox 360 controller support and fullscreen modes.
+
+How to run the game
+-------------------
+
+To run Mr. Rescue you will need the awesome LÖVE framework.
+
+You can download LÖVE for free at http://love2d.org  
+It only takes a minute.
+
+Most Linux distributions also have LÖVE in their software repository.  
+Search for "love" or "love2d".
+
+If you have LÖVE installed simply double-click the .love file to run the game.  
+If you retrieved the source code directly, just zip the whole folder and change the extension to .love.
+
+How to play
+-----------
+
+We highly recommend checking out the ingame how-to but here’s the basics:  
+* Your job is to rescue civilians from a burning building.
+* You rescue people by picking them up and throwing them out the window.
+* Equipped with a water gun you must fight your way through flames and fire sprites but remember: your job is to rescue people!
+* When being near fire your suit will accumulate heat. Collect coolants to keep it from overheating.
+* You water tank only has limited capacity. Emptying it will make you water gun overheat so watch your water usage.
