Elasto Mania Remastered

Boot up the game. Complete the 4 tutorial levels and Level 1 in the Original Levels collection. You will then have access the Stolen Internals collection. Complete all 54 levels. You may skip up to 5 levels at a time so if you are struggling, skipping the level is an option. You will have to come back and complete the levels you skipped to get the achievement though. I recommend completing the other collections first as this one is pretty hard. Good luck.
