Dungeon&Web

You must get out of the dungeon, to do this you need to find the key to each door, but the keys are hidden and it is difficult to get to them.
Beware of the web, it is poisonous and can kill you. Shoot it with fireballs.
Mana for fireballs is bottled and hidden in the dungeon as well as health.
And of course, don't fall into the lava, it hurts.

WASD - for movement
SPACE - for the jump
LMB - to shoot fireballs
