Emotion Mask - Concept Art

This game will be called Emotion Mask and basically your stuck somewhere and weird aliens will kill you or something if they catch you so you put on mask to disguise yourself.

My first idea is to have buttons for the mask that you click or like press keys to put them on but for now I'm thinking only buttons.

My second idea is to have people which are blue, yellow, green and more but you have to put on a mask to match the group so you don't get caught.

My third idea is to have a helicopter rescue you when you survived long enough.

That is all I can think of but there will probably be a lot or slight changes or additions when I start making a game. 

(Also I used a simple paint software like microsoft paint on the computer so the art looks bad)
