It is easy to get started - you fly around, shoot some stuff, collect some other stuff, and dodge enemy bullets, all while admiring the trippy scenery and self-repairing by flying close to stars. When you're comfortable, you can set difficulty to "Insane" (press esc) for faster paced gameplay. If shooting up stuff is not your thing, maybe you'll like using it in editor mode to create unique fractal artwork (you'll need to buy full version to be able to save easily).
