Centipede is a 2D vertically oriented shooting arcade video game published by Atari, Inc. in 1981. It was designed by Ed Logg and a female game programmer, Dona Bailey. The main objective of this game is pretty simple, the player just need to defend against swarms of insects, and he/she can complete the stage after defeating the centipede which always move closer to the player ground.

Tips: try to survive by dodging and killing distractions (insects)

Briefing...

Gameplay

This is how the gameplay looks like at the level 1. There is a centipede moving to the player ground, and a spider distracts the player. Player can only move around on the player ground, and can only shot upwards.

1. Red arrow = showing the score (earned after defeated insects)
2. Green arrow = showing the current stage/level
3. Black arrow = showing player's life (given 3 life for each level)
4. Yellow arrow = the centipede (must kill)
5. Orange arrow = other insects (distractions)
6. Yellow star = the player
7. Oval blue = player territory (player ground) 

Interactivity - Core game mechanic or action

The action involved in this game is shooting using SPACE button on the keyboard, and move along the player territory using W,S,A,D or UP,DOWN,LEFT,RIGHT on the keyboard. 

Concept and Setting - Big theme

Theme of this game is being in a jungle, defending a camp (i my opinion) from brutal attacks of various insects.

Goal 

The goal of this game is to survive at each level and get the highest score among other players. 

Challenge

The challenge of this game is to dodge and then kill every insects on the field. More insects are coming at the higher level, and those are getting more annoying since they move faster and faster.

Story

I do not thing that there is a story element within this game.
