Press the green flag to start the game. Once you die or win the level, do NOT press the green flag again. Use W to jump, A to go left, D to go right and left click to shoot. You will get achievements by doing special things. You will level up by gaining EXP, found by killing bosses and their minions. Levels get harder as they get higher, so be smart and do what you think is best for you. Most of all, have fun!
