+## Methodology
+
+![Letter Hunt](./../Misc/data/Analytics_Design.png)
+
+### Step 1 - UnityWebRequest
+Collect data during the game. When the player dies / level ends, send the data using a UnityWebRequest API’s POST request to MongoDB Realm endpoint.
+
+### Step 2 - MongoDB Realm App Service
+Create an App Service function to serve an end-point (this service has access to the Atlas cluster created to store the data). The function gets the data from the received request, creates an object, and sends it to the MongoDB Atlas cluster.
+
+
+
+
+
+### Step 3 - MongoDB Atlas
+This cluster stores the data received from the App Service function.
+
+### Step 4 - Python Matplotlib
+The data is exported as a JSON or CSV file. The Python Matplotlib package is used to generate charts and to analyze the data. The packages like Numpy, Pandas, etc are used to support this process.

+#### 1.3 General Description
+The game involves collecting the letters displayed around on the map/arena that helps form the word required to pass the current level within the given amount of time. You will have a weapon and appropriate ammunition and will also have to ensure you don't get killed by the enemies present. The game starts with the player requiring to form a 3 letter word and the level of complexity increases as the game progresses.

+
+## Game Mechanics:
+The player can move on the screen using WASD or the arrow keys. The player can jump using the up arrow or W key. 
+The player can also shoot using the spacebar and aim using the mouse.
+Letters are randomly generated throughout the level. The main goal is to move around the screen and collect letters to form the target word. 
+While doing this, enemies will follow the player. The player is responsible for avoiding the enemies. Each contact with the enemy reduces the health of the player. 
+The player can shoot and kill the enemies.
+The game also has 3 power ups that are spawned randomly throughout the level- 
+
+### Highlight Letters
+
+This powerup highlights the correct letters for a few seconds. This can help the player to locate the right letters to form the target word.
+
+
+### Destroy enemies
+
+This powerup kills all the enemies on the screen at that moment. This gives the player a few seconds to freely collect the letters without worrying about the enemies.
+
+
+### Increase time
+
+This powerup adds 5 seconds to the level.
+
+ The level will end under the following conditions - 
+The player is able to guess the right target word. In this situation the player will move to the next level.
+The player runs out of time
+The player completely exhausts his health and dies.
