BoxBoy! + BoxGirl! Cheats For Nintendo Switch

1. Unlock "A Tall Tale"

   Once you complete the "A Tale for One" solo campaign, "A Tall Tale" becomes available in the main menu. This stars Qudy the rectangle and contains his own unique puzzles.

2. Unlocking Play Stats and Ranks

   As you play, you'll be able to unlock ranks and statistics for your performance. Collecting all crowns and reaching all box targets in a single chapter will unlock them in that chapter's menu.
   
   Doing the same for all chapters will unlock overall player stats for the entire campaign. This can be found in the pause menu when selecting a stage.

3. HAL Rooms

   There's one secret HAL room in each of the campaigns.
   A Tale For One (Level 1-1): to the left of the starting position. The Box+ and Jump+ items are needed to reach it.
   A Tale For Two (Level 8-5): in the starting position, place one character on top of the other, then make a vertical box pile with the one in the ground and jump. Eventually, platforms will show up from the top.
   A Tall Tale (Level 13-7): there's a ledge to the left of the exit door that you can hook into.
