-# Arduboy
-This is a repository for my projects with the Arduboy, a tiny arduino based gaming handheld.
-You can browse different projects by browsing through the branches.
+# Spacemania 2000
+This is the shooter game from the book HTML5 Games: Novice to Ninja by Sitepoint. 
+[You can find the book here.](https://www.sitepoint.com/premium/books/html5-games-novice-to-ninja)
 
-Screenshots and other info will be hosted on [ARNweb](https://arnweb.nl/projects/arduboy/ "Arduboy projects")
+I rewrote the game in C++ because I want to learn a new programming language and this seemed to be a nice way to practice.
+
+## Getting it yourself
+The game is very unfinished at this point, but you can try it anyway. You'll have to compile it yourself.
+### Requirements
+* Arduboy, Arduboy compatible device or emulator
+* Arduino IDE
+* Arduboy2 library
+* Computer
+Start the Arduino IDE and load up arduboyTest.ino and send the game to your device.
+
+### Controls
+* A = Start, shoot and restart
+* B = Spawn enemy
+* D-Pad = Move
+* A + B = Reset game
+
+## TODO
+* Automatic spawning of enemies
+* Pauze menu
+* Different stages of difficulty
+* Music
+* Background image
+* Cleaner code
