"Size Matters " is a first person action-adventure platform video game . Set in the not-so-distant future, the main character must complete objectives using their special ability to grow or shrink. The player can choose to be stealthy or aggressive in order to accomplish their objective. The player will not be forced to use specific sizes and multiple ways to complete the level will be accepted. Enemy humans will always be normal size, but will become progressively more crafty at dealing with the player, whether they decide to become bigger or smaller. In example, if the player decides to go small and sneak through vents, the enemy will "learn" to put sensors or lazers in there. If the player decides to become huge for added strength, the enemy might start learning that rocket launchers or armor piercing rounds will work better. A player could therefore be mostly small and stealthy the whole game, and since the enemy is unprepared for anything else, then become huge and bulldoze their way through. In this way, the player can be encouraged to try out different ways of completing different levels, as well as add in higher replay value.
