Ultra Hat Dimension is a cute turn-based puzzle game with a top down perspective. Find magical hats to navigate through the levels of the Spluff Palace. Avoid getting punched and and put an end to Fab's reign of unfashionable terror!
Every stage has a key and a door. The objective is to first get the key, then use it on the door to complete each level. Spluffs, the blue blob-like creatures wearing various hats, will get in the way by punching anyone who wears a different hat than they do, both the player and each other.
Every floor contains hats that the player can use to order Spluffs with the same hat to move, consuming the hat in the process. Using hats to manipulate Spluffs around the map is critical in being able to get to the key and reach the exit.
The main game consists of 5 floors. The first 4 floors have 15 stages each, and the last has 6 stages with a final boss fight. Stages can be endlessly replayed from the menu once unlocked. The game also supports an option for custom maps made by players.
