Sonic the Hedgehog (16-bit)

Introduction
The first Sonic game, it starred just Sonic and Dr. Eggman. It was a simple sidescroller, where Sonic could curl up into a ball, whereupon if he hit an enemy, it would usually be destroyed. Sonic's jump was also a vital part of the game, as it was his main attack.
Each Zone featured three "acts" or levels each following the same theme as the last.

Ring bonus at end of level: 100 points for each ring held
Time bonus at end of level:
-Game clock reads 0:29 or less = 50000
-Game clock reads 0:30 to 0:44 = 10000
-Game clock reads 0:45 to 0:59 = 5000

End-of-level flags: On the screen where the goal post stands, there are sometimes flags you can trigger. These flags are hidden, but if you hit them they will appear and show either 100, 1000, or 10000. The flags that say "100" are really only worth 10 points each, but the 1000 and 10000 flags report their values accurately.
Special stage: 100 points for each ring held
Note: in cheat codes, a + signifies that the buttons should be pressed simultaneously.
