Practice Mode

Practice Mode can be activated during a runthrough of any Level except the Tutorial by placing a Flag. In this mode, the most recently placed Flag acts as a checkpoint, allowing players to practice sections that they're bad at in order to practice doing them. It can be quit in the Pause Menu, which starts a new attempt from the beginning. Upon completion of any Level in Practice Mode, the game will tell the player to "Now try to complete the level without Flags!" In addition, each Level has an independent progress bar in the Stats for its progress in Practice Mode, so it can be assumed that No Flags progress is more valuable than Practice progress. There are also separate achievements for Practice Mode completion, featuring an image with a Flag. (Completion of a No Flags runthrough does not obtain the respective Practice award.)
