Your weapon is your fireball magic spell, which requires mana to cast. Mana potions can be found around the levels, but your mana will refill as the time passes. To finish each map you have to find its exit, which is always heavily guarded and usually behind some locked areas. To unlock areas you must find the appropriate keys.
To increase your score, you can pick up treasure items which can be found around the levels. However the best treasures are hidden in secret areas ? these can be revealed by going near the wall where the area is and clicking on it (the cursor will become a hand as shown below). Killing monsters increases your score. At the bottom part of the screen you can see how many monsters are alive in the level.
The keys are:
Arrows, W/A/S/D: Turn, move forward/backward
Q/E or Space+Left/Right or Space+A/D: Strafe left/right
Shift: Turn 180 degrees (quick turn)
Tab, F6 or Page Up (depends on browser): Switch to fullscreen mode.
Left mouse button: Interact. Use the mouse to aim on the screen and move the cursor over the items. The cursor changes depending on what will be performed if you click:
Arrow ? You cannot interact with the item
Hand ? Pick up the item, or open the door
Aim circle ? Attack the monster with a fireball
Crossed circle ? Currently you cannot interact with the item.
