My Sonic Shoes

Essential to the gameplay are the golden rings the player collects along their way in each level; a feature which would become one of the defining characteristics of the series. These items are regularly placed around the level map and serve multiple functions. First, the player collects rings to protect himself. As long as they have at least one ring, the player will not lose a life when injured. Instead, when hit, up to 40 of the rings the player has collected will fly outward and scatter around the immediate area, some of which can then be retrieved before they disappear. If the player runs into an enemy without a single ring, they will lose a life. If the player collects 100 rings they will gain a life, and gain an additional life for every 100 rings after that, provided the rings are not lost.

If the player has at least 50 rings at the end of an act, a giant golden ring will float above the finishing sign which can be jumped through to enter one of the special stages. (This excludes the final act of a stage, when Sonic will enter a boss fight). At the end of each act, the total number of rings the player has is multiplied by 100 and added to the player’s score. During the score-tallying, the player can also jump through the air to find hidden emblems which can range from 100 to 10,000 points. This was the only console Sonic game until Sonic Adventure where the player could get more lives by collecting over 200 rings (acquiring 300 rings in the later 16-bit titles resulted in no additional lives).

Also scattered throughout each level are monitors which, when broken by the character, reward the player with one of a variety of bonuses. These include a shield which will protect Sonic from a single hit, a 10-ring bonus, an extra life, temporary invincibility (accompanied with a temporary change in music), and “Super Sneakers”, which give the player a temporary speed boost (and increase the tempo of the music for the duration). The item monitors have become another long-lasting feature in the series, though they have been changed to bubble-like containers in later games.

Despite the various types of protection available, neither the shield, rings, or invincibility will prevent the player losing a life if Sonic is crushed (by a trap or between a wall and a moving platform), drowning, running out of time (each act has a ten-minute time limit), or falling into a bottomless pit.

Progression through the game is made easier for the player by lamp posts that act as checkpoints. When Sonic passes a lamp post, its color changes from blue to red, and the next time a life is lost, gameplay will restart at that point rather than at the beginning of the act. If a checkpoint is activated and a life is lost as a result of running out of time, the time at the checkpoint will reset to 0:00.

Hazards the player experiences include a wide variety of “badniks” - these appear as animals trapped inside mechanical bodies which are released the moment the player hits them. Each badnik takes one hit to destroy, but they vary greatly from Zone to Zone; some will walk in a set path, others will try blasting the player, and some cannot be avoided at all. The player must also avoid rows of sharp spikes, cliffs, and elaborate death traps. There is also the threat of drowning, as the player can only survive 30 seconds underwater (locating air bubbles can extend this).

The game features no game saves or passwords. This means that the game has to be restarted from the beginning when the player runs out of continues or turns off the system unless the player uses a cheat code to access the level select screen. This is Sonic’s first-and last-solo adventure on a console game until Sonic and the Secret Rings in 2007.
