Let's Do That Again Achievement
Let's Do That Again5
Beat your previous score on a level
This achievement can easily be gained on the first level in chapter 1, although any chapter/level will work as well. Basically just make sure your movement count is very high for the level (switch back and forth between blocks often before uniting ilo and milo) and then complete the level. Once completed, select the level again and this time unite ilo and milo while taking less steps than you did previously and the achievement will unlock.
