Jet Set Willy

Platform game where you control Willy through dozens of interconnected rooms in his mansion, collecting scattered objects to complete the game. You can tackle rooms in any order—there's no set path through the house. Each room presents different layouts and hazards you'll need to jump over or avoid while managing Willy's limited energy. The mansion includes kitchens, gardens, attics, and stranger spaces, each with distinct obstacles and collectibles. Movement is precise: mistimed jumps or collisions with enemies drain your energy bar. You'll memorize room patterns through trial and error, figuring out safe routes to grab items without getting hit. The non-linear structure means you can skip tough rooms and return later, though you'll eventually need to clear everything. It's a test of platforming accuracy and spatial memory across a surprisingly large house.
