Description
After being captured by the ghosts of last year, our sorcerer has been locked in a jail in the basements of the witchâs castle. After several months, he decides to escape. He can still shoot fireballs. And, because of the darkness, he uses a spell which produces a light above him, but it runs out over time. To revive it, he needs to kill creatures. So pay attention to his intensity...
To go upstairs through the 5 levels, he has to collect the coins scattered all over each one.
Good luck !
Instructions
The UI
- green bar is for life level
- white bar is for light intensity

Game Controls

The player can move freely, but when you start shooting, the shooting direction locks until you release the fire key.

| Thanks ! I don\'t know books about voxels, but Google helped me a lot. Come on Java-Gaming.org, there are lot of discussions on cube world and used techniques. | ||
