Check points
You can progress if you have earned at least one point per level until you reach a checkpoint. The first checkpoint appears after level 9 and requires 18 out of a possible 27 points from the previous levels to unlock. The second and third checkpoints appear after level 20 and 31. Both of them require 24 points out of a possible 33 points to unlock.
Exits
Before you begin moving in a level, locate the exit. At times they may be behind crates or other objects. Rotating the view if necessary to find it. After locating the exit, work backwards to find the optimal path through the level. This will allow you to check if you have enough pieces for your desired path, and to find which components you need to reuse. When you have two characters in play, you will begin controlling the other character the moment the first one goes through the exit. When trying to avoid falls or triggering an elevator, you must move that second character to a neutral space before allowing the first character to exit.
Puzzles
Each puzzle features combinations of objects that must be used to reach the exit. Ladders: After placing a ladder, you do not have to wait to for your character to get to the top or bottom before moving another object. Ladders will expand to the tallest block in front of it, as long as that block can be moved upon. A ladder can bridge an immovable or non-traversable block, allowing you to bypass obstacles. Crates and boxes: Crates and boxes can be moved around on a grid without touching other elements. Start by testing a crate to check how high you can move it. At times you can place it higher than the existing structure. Crates can be moved up, down, forward and back, but cannot move around a corner. Look for the "L"-shaped blocks in order pass gaps. Cracked Blocks: You can only cross a cracked block once before it breaks. Place cracked blocks between intact blocks in order to get the most distance and give yourself a safe place to stop. Do not to place a cracked block directly next to an exit or you will fall through before you can leave. Elevators and buttons: When both Tamino and Papageno can be played, sets of buttons and elevators that each can trigger will appear. Move between characters quickly to trigger and utilize elevators, while making sure neither becomes stranded without a way to ascend or descend. You cannot operate an elevator if the other character is standing on a button already. You must move them away before switching characters. If an elevator is moves past the block you need it to reach, move a crate above the lift to stop it at the desired height. You can then move the crate out of the way.
Scoring
When a level is completed, a flute will appear with opened and closed holes. This indicates how many points out of the three possible that were earned. There are multiple ways to complete each level. Points are awarded based on how fast the level was completed. One point is awarded just for completing it. The other points are awarded on your speed. There is no visible timer, and no way to tell how well you have done until the level has been finished.
