you use the mouse to click and enter areas and the space bar to attack, flee is controlled by the back arrow. the other moves will be taught to along the way. the objective is to beat the Zombie Dragon (which is the final boss) and save the world. (This part is meant to inform you about the classes and abilities) the different classes only change your starting stats. Warrior is mostly balanced but has very low magical stats, Thief is very fast but has low in most stats, Monk has very high HP (life) and Atk (Attack)and they are also very skilled in hand to hand combat, Red Mage is very balanced and can use both types of magic but they can't use some of the higher level spells, White Mage is a very weak class but has high MP (magic points) and can use strong healing magic, and Black Mage is very weak but not as fragile as a white mage but they can only us black magic. Learning magic is also a little weird, you need a certain amount of a stat to learn a spell, white magic is magic defense and black magic is magic atk. the martial abilities are learned through getting Atk.
The way to level up is by clicking the character. This game is a turn based RPG so the game is going to be difficult. the many different skills that the commands tell you how to do are unlocked by increasing certain stats.
