Suggested Characters: RunnerFront ChildFront LizardFront


This tunnel has fairly average gameplay, with most of the appeal coming from its interesting patterns and bright colors. All the levels of The Crystal Gallery are very large with a lot of different routes to success. The main tip is to time your jumps right and make it on all the platforms and you should be fine. Many characters, especially the Runner, are good for this tunnel. Some levels might have a specific pattern to them making it easy to complete.

There is cutscenes in this tunnel. More information can be

found on the Story page.


After beating Level D-14, a cutscene will begin in Level D-12 showing a conversation between the Runner and the Gentleman. The Gentleman requests to rename a few tunnels due to uninformative names, which the Runner reluctantly allows. Then she runs back through the tunnel while the Gentleman considers the different factors needed to make a good name.

Playing With Fire[]

The Skater meets up with the Child in Level D-3. The Child shows off some candy he found, to which the Skater asks if he could try one. The Child gladly offers one, saying he doesn't need them, and asks if the Skater likes candy. The Skater doesn't mind them and says you have to eat something at least, to which the Child goes on a little mini-rant about diets.

The Skater apologizes for setting the mood down, and insists they talk about something fun, which reminds the Child that they can instead burn the candy. The Skater asks if he can see it as long as the Child is okay with it. The Child happily obliges, saying that he has nothing else to use it for.

Parts 6, 7, and 8 from Emerald. 9 comes from Sapphire. At last, 13 and 14 come from Garnet. Hence, The Crystal Gallery.
