A variety of enemy types and power ups were added to keep difficulty varying throughout. The enemy movement patterns and shooting patterns are also designed with random variation in mind so even two identical enemies move and shoot differently from one another.

Puzzles were designed around wrinkles within the main mechanic. For example, since the sword needed to be able to pass through objects to return to the player, a puzzle would require the player to understand how the sword interacts with the world to figure out the solution. This was used to both teach the player more about their magic sword, how it can be used to interact with the world, and give players that satisfying "Ah-ha!" moment.
