The hardest level for the developer to design was Sky Battalion, as there were a lot of situations on the airships that were difficult to figure out in terms of making sure Lilac, Carol and Milla could navigate through them. Not only that, but the stage has four mini bosses instead of one and the end boss was particularly tricky to animate.

The most fun level to design was Fortune Night with its gimmicks and had the developer's personal favourite boss in the game.
