Back to Origins is a world of paintings in Rayman Legends which features levels from Rayman Origins, though altered graphically and in terms of level design, some skull coins in the original levels have been replaced with Teensies, while Purple Lum chains have been added in the stead of Lum Kings. Turnips have also been added to levels.
There are also a few differences between the levels featured in this mode compared to their original designs:
Some level names have been slightly altered.
Electoons and some Skull Coins are replaced by Teensies.
Due to the Lum rewards requiring twice the amount of Lums as in Origins (350 for a medal in Origins, 600 in Legends), many more Lums are present.
Some levels have had their layout modified slightly.
Some enemies from Rayman Origins are replaced by enemies from Rayman Legends, or their designs are updated (like Darktoons).
The Tricky Treasure Chest levels and the Mosquitoes levels are easier than the original game's, possibly due to updates to the physics engine.
