Common errors of nowadays players and SB specific notes:

1. Kill all enemies in all dungeon rooms, there might be a secret or item. You can safely expect one at dead ends, at the middle of long hallways and at
screens with different enemies than around there.

2. Keep the actual dungeon's item at hand. All spots that seem blocked or buggy literally have "use the dungeon item here!" written all over. Like, only
half of the blocks lowered after using a key? Use the hammer on the rest!

3. If something blocks your way, you need to remove it. Like if there's a spike before a door, just bomb it away. (Or ready the dungeon item...)

4. Free info rooms are rare, they are placed only when they really has something important to say.

5. Keep checking back to the Mansion of Republic.

6. Pay attention to when NPCs tell you should return to them.
