LeafeonZ is a simple pet sim whose goal is to prevent the creature's HP (HAPPINESS POINTS) from dropping to zero. Initially, the game system had only one huge button, and thus dead space was the biggest complaint to come out in play testing. Therefore, the entire thing was transformed into a gameboy-esque console interface, and the game developed from there. Finally, this was initially intended to be playable on mobile, but that never happened due to time constraints.
Note: While I did all of the art myself, I do not own the concept of Leafeon, or any other Pokemon-related ideas, nor do I deny that the interface looks like a hybrid Game Boy. The point was for fun, as a parody of sorts.
