Overview
Final Spark is a puzzle game about light. Players control a small orb of light that can move around in the worldspace, illuminating various areas. The objective of each level is to reach the end, which players can do by navigating the pitch-black levels.
Core Mechanics
The ball of light that players control is heat-sensitive. That is, the longer that the light stays in one place, the colder it gets. As the light gets colder, it slows down and dims. As the light gets dimmer, players see less. Therefore, it is in the player's interest to keep moving as fast as possible, to go as far as possible. The light illuminates paths through the game, allowing the player to navigate easier the brighter the light is. As players progress through levels, there are multiple paths that they may take, as well as waystations along the way that they can visit. Passing through a waystation allows the ball to fully charge up, while also providing a boost of movement speed. Waystations also act both as checkpoints and makeshift navigation aids, allowing players to see where they have already been. The final point that a player has to make it to is not indicated for the player - they have to find their own path through the maze.
Visual Style
Final Spark is a very desaturated game, with the majority of the game map being a simple combination of black, with white lines indicating the path through the maze. The light itself illuminates the area around it in shades of white and grey, making the game easy on the eyes while also being visually striking. With the game's core mechanics not being hugely affected by the visual representation, it makes it easier for the player to concentrate on navigating the maze while also appreciating the simplicity of the visual design.Final Spark utilizes shades of white and grey to emphasize a different visual style, similar to LIMBO.
