The Magic Candle

In the game, players must assemble a group of six adventurers and journey across the kingdom of Deruvia to keep the demon Dreax imprisoned in the eponymous magic candle, which has begun to melt. The game’s world includes several towns and cities, two castles, and several dungeons and towers. Unlike many computer games, one wins not by defeating a final enemy, but by collecting the necessary items and learning the necessary chants in order to preserve the magic candle.
The game has 3 difficulty levels changing the number of in-game days you get to complete the game in. A lot of travelling, dungeon-crawling, town-exploring, and especially, lots of conversing with NPCs.
