Notes

Given the circumstances, the scenario is quite challenging. Let’s break down the best approach to maximize your chances of finding the cash and safely exiting the room while keeping in mind the various dangers and restrictions.

### Step 1: Create an Exploration Algorithm

1. **Initial Setup**: Memorize how far your chair is from the walls and doors, making mental notes of your steps as you stand and feel your way.

2. **Exploring the Doors**:
- Choose a specific direction to navigate toward the doors (for example, East).
- As you move, take deliberate steps, counting each one. For instance, take 5 steps towards the East door, then stop and feel for the door handle.
- If there’s no handle or door after the 5 steps, backtrack to your chair position.

3. **Testing Doors**:
- If you reach a door, step through into the vestibule and shut the door behind you.
- Once inside, you will experience one of four outcomes (danger, cash, open corridor, or viscous dog):
- **If you find cash**: This might feel like a risk since it will trigger spikes, but the key is that you still know how to get back to your center.
- **If you experience danger or the other outcomes**, backtrack and remember how many steps it took to return to the starting point.

4. **Repeat the Process**: Continue exploring the doors in a systematic manner, possibly trying the next cardinal direction (West, South, North) until you've tested each one.

### Step 2: Finding the Cash

Assuming you find the bag of cash, and the spikes activate:

1. **Immediate Action**: Grab the bag of cash quickly.

2. **Navigate Back**: Immediately recall your steps back to the center. If you took a total of 5 steps to reach the cash, take 5 steps to return to the center of the room using the same method you employed before (counting each step).

3. **Mindful of Spikes**: As you exit the vestibule with the cash bag, keep your arms in front of you and concentrate on your path back, remembering that the spikes are protruding and require careful movement.

### Step 3: Choosing the Exit Door

After successfully navigating back to the center:

1. **Reassess Your Directions**: You will now need to choose a door to exit. Remember, you can either turn left or right (90 degrees from your position):
- Based on your earlier exploration, you can choose either door (for example, the left door could lead to the corridor, and the right door could potentially lead to danger).

2. **Decision Based on Your Exploration**:
- If any door is memorized as the corridor from your exploration, choose that door. If not, you may have to rely on your intuition or a random choice at this point.

### Important Considerations

1. **Maximize Memory**: Your ability to remember your steps is critical and helps avoid deadly outcomes.
2. **Intuition and Chance**: Given the total darkness, intuition plays a vital role, especially after multiple trials. You must lean heavily on your mental mapping.
3. **Path Awareness**: Always remain steady and aware of your body positioning in relation to walls and doors – this limits the chance of bumping into spikes if you encounter them.

### Sensing Your Surroundings

1. **Feel and Listen**: Without vision or sound, use your sense of touch more purposefully. Run your hands along the walls to understand their contours and feel for openings.
2. **Count Steps and Monitor Breathing**: Use your breath as a rhythm to help you remain calm and focused while counting steps. This will help maintain spatial awareness of your distance traveled.

### Final Thoughts
The challenge is about careful exploration and memory. The risks are inherently high in this game, so utilizing strategy, intuition, and memory will be your best tools. Good luck!
