Eternal combo

While a character is in the air, hitting enemies increases a hidden counter that decides how many points to award. The first few enemies are worth 100, 200 then 500 points, then the next few are worth 1000. Eventually, enemies are worth 10000 points.

The counter resets when a character lands back on the ground. But if enemies are hit with a rolling attack and the player never goes off the ground, the counter never resets - rolling back and forth in areas with regenerating enemies such as the ink-stamp rabbits in Press Garden Act 1 can let the player max out their lives counter at 99 quickly by collecting vast amounts of 10000 point awards (an extra life is awarded every 50000 points).

Sign collision detection

The Signpost has faulty collision detection - in several acts (most notably Metallic Madness act 1) with ceilings it is possible to drive it into the ceiling, causing it to vibrate in a glitched manner until it falls out of the ceiling. With persistent effort, it is even possible to drive the sign entirely into the ceiling, causing it to be placed within it.

Knuckles in Mirage Saloon glitches

Using Debug mode, Knuckles can access Sonic's version of Mirage Saloon act 1. This leads to at least two glitches;

  • The cutscene where Heavy Magician knocks Knuckles off the Tornado sees the Heavy knock a 'GOT' off the Tornado instead.
  • When Knuckles finishes the cutscene at the end of the act, he glitches back to where he normally starts act 2.
