Find your way through Minos' Maze!
Avoid enemies until you find a sword shard (found in big rooms identified by a yellow ground and a blue pedestal). You can place chalk marks on the floor to mark rooms you already visited and paths you already took.
Once you found a shard you can kill small enemies, hit the boss to slow him down and destroy props (pods, trees, skulls, etc.) to find hearts that replenish your health.
When you found 3 sword shards you can attack and kill the minotaurs and win the game.
