Sonic – Code Gray game description
Sonic 1 – Code Gray plays as a 2D side-scrolling platformer. The gameplay centers around Sonic’s ability to run at high speed through levels that include springs, slopes, high falls, and loop-the-loops. The levels are populated with hazards in the form of robots (named ‘badniks’ in the Western game manuals) that Dr. Robotnik has trapped animals inside; destroying one frees the creature, but is not necessary to complete the game.
The player must also avoid touching rows of sharp spikes, falling into bottomless pits, and being crushed by moving walls or platforms, as well as drowning, which can be circumvented by breathing air bubbles periodically released from vents.
Sonic’s main means of attack is the Spin Attack, in which he curls into a ball and rotates rapidly, damaging enemies and certain obstacles upon collision. This can be performed by jumping in the air or by pressing down on the D-Pad while moving on the ground.
Scattered around each level map are gold rings. Collecting 100 rings rewards the player with an extra life. Rings act as a layer of protection against hazards: if Sonic holds at least one ring when he collides with an enemy or dangerous obstacle, he will survive.
However, all of the rings in his possession will be scattered; they will flicker and disappear in a few seconds if not picked up again. If he is hit without holding any rings, then he loses a life.
Shields and temporary invincibility can also be collected to provide additional layers of protection, but certain hazards, such as drowning, being crushed, falling down a bottomless pit or running out of time, will cause Sonic to lose a life regardless of rings or other protection.
Game zones in Sonic – Code Gray
The game is split up into six zones-named Green Hill, Marble, Spring Yard, Labyrinth, Star Light, and Scrap Brain-each with its own visual style and enemies. Each zone is split into three acts. The player must navigate through each zone to progress.
At the end of each zone’s third act, the player confronts Dr. Robotnik, who pilots a vehicle, in a boss fight. After completing the sixth zone, the player continues directly to the ‘Final Zone’ for the last encounter with Robotnik.
The player is given three lives-although powerups and rings give more-which are lost when Sonic collides with hazardous enemies or objects while having no rings, falls off-screen, or exceeds an act’s ten-minute time limit.
Lampposts that act as checkpoints allow Sonic to return to the most recently activated post when he loses a life. If Sonic loses a life as a result of time running out but has another life, the time will reset to 0:00 when he returns to the checkpoint.
If all lives are lost at any point in the game, the ‘Game Over’ screen will appear, at which point the player can return to the beginning of the act with three lives if the player has any continues.
