Fog Castle provides an introduction to game mechanics.
Introduction[edit]
The game start with Django approaching Istrakan, and starting with an exposition of backstory. Read it as necessary, and continue to the north-east.
Crossing the bridge will shoe the time and time remaining to sunset. Make sure you have enough light for 20 minutes of gameplay, as you cannot complete the castle when it becomes dark.
Pile Driver[edit]
The first location will introduce the Pile Driver. This causes a bright flash, and reveal where you need to bring a coffin. Continue to the northeast.
Land bridge[edit]
At the land bridge, you will be circled by a few ravens, which may attack. You can easily run past them without difficulty.
Courtyard[edit]
The castle's courtyard will contian spiders. They will mostly run away when attacked, but will lay webs to catch you.
The chest contains a green apple.
Enter the door to the left to enter the castle.
Lower floor[edit]
The first room is a simple turn around the corner. Aside from a tutorial marker, there's nothing of importance.
The second room contains a solar station. It charges and stores energy as you play the game in the sun, and can be drawn from to work in dungeons or during the night. To retrieve energy from the device, press 
.
The third room contains a Knight solar gun frame. This allows you to make a short-range spread attack, which is useful if you are swarmed. The tutorial panel will also mention Solad Bamboo shoots, which are created when you use your waepon in a dungeon or castle.
Upper floor[edit]
The second floor introduced you to the first enemy, a Bok. While you aren't required to evade or destroy it, it is very dangerous if it detects you. It unleashes Klorofolun in a spread pattern, which will quickly converge on you - it must be shaken off or steralized with your gun. The undead can be destroyed if it's forced or tricked into the skylights, but can still be defeated using regular weapon fire.
The south exit leads to a balcony where you can quickly rechare your weapon.
Re-enter, and the first chest contains a Life Fruit.
The count[edit]
Continue up the stairs to eventually reach the count. He is in the coffin, and there are bats that fly around. Repeal any nearby bats, and press near the coffin to start dragging it.
Drag the coffin back to the pile driver mentioned earler. Enemies will respawn, and some vacant rooms that were empty will also contain Boks. If the coffin starts to shake, shoot it a few times to calm it down.
The vampire[edit]
When you bring the coffin into the pile driver, charge the two generators with the solar burst (from the knight frame). Activate the purification process, and make sure the generators remain at full power.
When the vampire is destroyed, you will be shown a rank screen describing how well you did. The rank is based on the amount of time in the mission, the number of times you're spotted by an undead, the number of times you dies, and the amount of energy charged during the mission.
