Glitches

In Smash Hit, there are multiple glitches that can happen. Here is a complete list, and their respective images.

Random Rooms Glitch
This glitch was discovered on the multiplayer game-modes update. If you close the game while in checkpoint 2 mayhem mode stage 1 part 2 (2-1-2) and Checkpoint 2, stage 3 or 4 (2-3 or 2-4), after this the checkpoints are all jumbled up. The mayhem boss can appear somewhere in endless after one or more re-opens.

However, the score/distance will not be changed by this. The Checkpoint subtitle is incorrect though, the game crashes in versus or co-op mode and you fight the Bosses again in mayhem mode. This glitch is very unusual, but also the easiest to get, and the most accessible.
 * Rooms (and sometimes their parts) are connected together randomly, so you might see big walls, and other features you might not usually see, obscured by the stone blocks in the actual game.


 * Each "part" is considered a room in it's own right, so halfway through a 2- or 3-part (Checkpoint 10 only) room, it might suddenly go somewhere else.

How the Checkpoint subtitle works:

Suppose you are in Checkpoint 2 Stage 2 and the glitch happens.

Though you are in a different checkpoint (e.g. 7,), you were previously in Checkpoint 2, so Checkpoint 3 is used as a marker. The next marker is Checkpoint 8, although you are in Checkpoint 5, really. The marker is from the previous (real) checkpoint you were in before. It is tricky to understand, but reading the table, you might understand better.

Repeating Glitch (Room Of Purgatory)
There is also a automatic repeating glitch. This is a glitch only occurs via the wrong checkpoint glitch although this only occurs at a distance of 30000+, because of that , it is referred as the Room Of Purgatory. 

Now Entering Endless Mode Text Glitch
This is also a automatic glitch. This can only occur via the wrong checkpoint glitch and it is extremely-extremely-extremely rare. Usually occurs before a distance of 12K.

Disappearing Crystal Glitch
Sometimes, in a Random Rooms glitch, the crystals might not appear where they should be. This is most evident in pedestals, blank spaces, etc, anywhere that can hold a crystal.

Disappearing Room Glitch
Though extremely rare, rare on zen mode and possibly on only some devices , the Disappearing Room glitch can occur at any time , although it is extremely-extremely rare for blank door before the disappearing room glitch occurs. First, the next stage you enter will not have anything visual, except the balls you throw, powerups, shadows, the door outline, and the background color, there is also a blank door at the end. After passing this level, the next level might consist of nothing. No solid surfaces, no objects, no music... just the endless abyss of echoing after throwing a ball, and a white background. 

Stop Glitch
The stop glitch can randomly occur anywhere (at the beginning of a stage). Sliding objects and your progress will idle, while balls and objects with gravity continue to move. This likely occurs because of music failing to load, thus you can also cause this to occur by playing an alarm on iOS devices in the middle of a game. Exiting (not closing) and resuming the game will resolve the alarm-activated stop glitch.

Lose in the Credits/More Games Glitch
If you tap "more games" or “credits" in versus and co-op mode, by throwing balls you can drop to zero and lose.

Reset Powerups Glitch
This is an automatic glitch. If you close and reopen the game after you acquire a powerup, your powerups will not save, same with restarting from a checkpoint after you had powerups, even those you acquired before the checkpoint.
