I have been doing some mind mapping expand on some of my ideas of what may go in my game.
This is were I started off with my 2d Tower Defence Game in the centre.

Here are the graphic choices what I thought would be appropriate.

Here are the enemies and what may associate with them.

Here is the character and what abilities it may have.

Here is what the scenery may consist of in the background if I am to implement any of these into the game.

Here is what the weather may consist of if I am to implement it into my game.

In conclusion I had thought of some ideas which I may or may not implement into my game but it has defiantly helped me expand my thoughts of what I may end up putting into my game with some many creative ideas of what I may potentially do from the environment to the weapons, I will take every detail into consideration to make sure I use this mind map to map out my game design as well as I can make it.
