About Harley's Humongous Adventure
Harley's Humongous Adventure came out for the Super Nintendo Entertainment System in 1993, developed by Visual Concepts. It was one of many platformers on the system, a straightforward action game from that era.
You control Harley, a kid inventor who has to rescue his friend from aliens. You run and jump through levels, but the main draw is that you can shrink yourself down to a tiny size. This changes the entire perspective of the stage, letting you walk on tables or through keyholes to find new paths. You also get a jetpack for limited flight, which helps you reach higher platforms or cross large gaps. The game is not particularly easy; the levels are large and demand careful exploration. It feels like a puzzle box where you are constantly switching sizes to figure out the correct route forward.
