THE GAME
Explore the mysterious castle full of monsters and secrets in a quest to collect all the treasures (that will also protect you from the curses on your way) and crush the main boss. The game won't let you exit the castle, no matter how you try. Technically you can win, but there is no end.
CONTROLS
Press Enter to start the game
Press 1, 2 or 3 to select a hero
Strength, Intelligence and Dexterity at the hero selection screen are the maximal values which that hero can get. Strength is both for life and attack power, intelligence is both for mana and spell power. Dexterity affects your attack and defence accuracy.
You lose the game when either of those parameters gets below zero!
ON THE MAP
Arrow keys to walk around
Z or Enter to perform action (attack, open chest, read book, buy potions, use the stairs, gaze into an orb, drink from a pool)
X or Space to cast spells in battle or to light a flare otherwise
1, 2 or 3 to select a potion to buy or a spell to use
Press M to turn background music on/off
ARTEFACTS AND CURSES
Opal VS Blindness - you forget the map and don't see any new rooms, flares become useless
Pearl VS Forgetfulness - you don't remember where have you been before
Ruby VS Lethargy - monsters get the first turn to attack
Diamond VS Weakness - you lose 1 strength point every 20 turns
Emerald VS Bad luck - your minimal attack power drop to 1 instead of 50% of strength value
Blue Fire VS Bookstuck - book sticks to your hands and you can't attack anyone in this state
Sign VS everything except Bookstuck
SPELLS
Web prevents the monster from attacking and lasts 0-3 turns. Costs 1 point of intelligence.
Fireball is obvious enough. Costs 2 points of intelligence.
IQ instantly kills your opponent if it's intelligence is less than yours. Otherwise, you lose. This spell doesn't spend anything.
