Platforming, pressing down to save on lights, exploring, and wonderful, wonderful ambient music. I play these games mostly for the music. The demo is pretty big, so I'd say check it out. If you like it, try Knytt and Knytt Stories. They're very similar. Also, WaDF is one of my favorite games ever. You're a ball, and you can change your mass/density/texture/elasticity to explore the world. Great indie games.
