Player bugs

Eternal combo

Sm-pressgardencombobug.png

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 1,000. Eventually, enemies are worth 10,000 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 Splats in Press Garden Zone Act 1 can let the player max out their lives counter at 99 quickly by collecting vast amounts of 10,000-point awards (an extra life is awarded every 50,000 points).

  • Present in Steam build ID 2077506

Not fixed in any version.

Sign collision detection

Notavailable.svg

The Signpost has faulty collision detection - in several Acts (most notably Metallic Madness Zone 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.

Not fixed in any version.

Knuckles in Mirage Saloon glitches

Notavailable.svg

Using Debug mode or the Dev Menu, Knuckles can access Sonic's version of Mirage Saloon Zone 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.

Not fixed in any version.

Angel Island Zone in Mania Mode

Notavailable.svg

Probably the most infamous glitch in the game. If the player turns on Debug Mode and presses the button (depending on the system) to enter object placement mode at the exact second before the first cutscene in Mania Mode, they are able to use debug during the cutscene. This works on v1.04 and in Sonic Mania Plus. They must place a Signpost and wait until the score summary finishes (if playing as Sonic, Tails, Mighty or Ray, they must make sure they don't exit out of object placement until the score tally appears; if playing as Knuckles, they must not exit object placement at all). Afterwards, they are taken to the actual Angel Island Zone.

The zone is the same, but the background is missing (instead it's the ocean). Some textures also go missing. The stage will correct itself once you go past the waterfall. The player can use debug mode, but if they go to the bottom of the stage and die, it will result in a Game Over. This is because the game thinks they are in Encore Mode, and Encore Mode uses a different lives system (and the player doesn't have another character). If they go to the area where Mighty and Ray are, the ocean is replaced with a really weird background. If they destroy the capsule without the Plus DLC, Mighty and Ray will become Sonic (their trapped animations are still there, though); if they have the DLC, then everything is normal. They can pick a partner, but they can't control them except when they place a Swap monitor. Once the player has full control, they should use debug to go the next cutscene. Th player must be careful of going down Mighty's pathway though, as for some reason the player can get a Game Over. Once the cutscene plays, the player will go to Green Hill Zone with the companion they picked. However, if they skip the cutscene, they will go to the Encore version of Green Hill and they can continue to play the Encore levels (note that if you do this, even though the zones will have the Encore palettes, the game will still think they are in Mania Mode, so monitors that are exclusive to Encore Mode are missing unless they place them with debug mode). The game can be beaten with any character and companion with the Mania or Encore Mode palettes.

This glitch was discovered by YouTuber Sonic Mania Architect, who made a video on May 6th, 2018, just a few days after the v1.04 update leak.[1]

Not fixed in any version.

Animation bugs

Tails intro animation in Chemical Plant

Notavailable.svg

For whatever reason, while Sonic and Knuckles have their own unique animations that would play when a chemical drop landed on their heads during the intro to Chemical Plant Zone, Tails did not have one, as he instead looked upward. An animation existed within the internal sprite sheets, but went unused.[2]

Fixed in v1.04/Sonic Mania Plus. The new animation is different from the unused one in earlier versions.

Moonwalking in Press Garden

Sonic the Hedgehog's Moonwalker

After defeating Shiversaw the end of Press Garden Zone Act 1, if the player runs to the far right of the area and faces left when the Signpost lands, the player will walk backwards during the intro cutscene to Act 2. This can happen with any character.

Not fixed in any version.

Heavy King intro with Sonic or Tails

Notavailable.svg

Using debug mode to cheat Sonic/Tails into the Heavy King boss arena in Lava Reef Zone Act 2 (located below and to the right of Heavy Rider's boss arena) results in the character glitching to Knuckles' sprites when remembering Eggman's theft of the Master Emerald and when demanding Heavy King to leave the shrine before attacking the claw-arm machine. The cutscene after the battle which sees Knuckles use a teleporter to reach Metallic Madness Zone is also skipped.

Fixed in v1.04/Sonic Mania Plus, due to the player having the option to fight him with any character in Encore Mode.

Mighty's victory animation

SonicMania MightyCapsuleBug.png

Mighty's victory animation is rather bugged in some cases. If he is standing on the Capsule at the end of some zones, he may fly off the capsule during his victory animation depending on where he is standing and which direction he is facing.

Not fixed in any version.
