Here is a guide on how to get all achievements in The Artful Escape.
Story-Based (Unmissable)
The Journey Begins: Leave Lightman’s workshop
Complete Heliotromms: Defeat Tromms
New Threads: Create a custom outfil
Complete GlimmerDimm: Defeat Glimmer
Complete Hyperion: Defeat GlamourGonn
Guitar Legend: Complete the Game
Missable
Stage Fright: In your first encounter with Lightman, in Calypso, do nothing for 3 minutes while the game tries to get you to press notes. This can also be done in many other places.
Snowman: Near the start of the 1st world, the Snow Mountain, there will be a single snowman in the background. Stop in front of its and play your guitar for a few seconds and the achievement will trigger.
How’d you get up there: Near the start of the 2nd world, the Desert, you’ll come across a water area with jelly springs. At the end of this section there will be a large jelly up onto a high plateau that has an arch above it and then a water slide immediately beyond it. Jump up high using the jelly and momentum and you can get on top of this arch without too much trouble. Stand on top for a few seconds and the achievement will trigger.
Amp Jammer: Throughout the 3 worlds (Snow, Desert, and Jungle) there will be circles with light coming up out of them, that you slam down on. Many of these are mandatory for progression, but not all of them. There are 1-2 in each area that are missable. Make sure to slam on every one of these in each of the 3 areas, and win the mini-game that appears after. This will trigger midway through the Jungle.
And that’s it. Fairly easy game to 100% in 1 playthrough. If anyone has questions, please let me know. If this helped, I do appreciate thumbs up and/or awards. Cheers!
