I've seen a few maps that are designed such that the map's preview is a recognizable image. While the "preview art" was well done, the levels weren't very fun to play. I decided to try creating a level that had a nice-looking preview while still being playable. Although the very limited color palette in the map editor prevented me from getting Sigrid's colors just right, I think the end result looks pretty good. In terms of gameplay, I decided to break the puzzle into multiple sub-puzzles due to the huge size of the map. The player must kill Loaded Thieves to gain money in the sub-puzzles, then spend the money in the final sub-puzzle. To make the map more cohesive, I set up events such that all the allied Sigrids share a groove meter. This forces the player to think about where to use Sigrid's groove and in which order to tackle the sub-puzzles.
Each type of terrain has a certain color in the preview. Some tiles, such as plains and carpet, change color depending on the biome. In addition, units and properties have nine possible colors (eight colors for the different teams, plus another color for neutral). However, there is a limit of 256 units and properties, so I couldn't use those nine colors very much.
In order to make the preview image look right, I didn't put units on the map normally. Instead, I spawned them and set their HP using events.
