Astro Botboasts a large and varied roster of levels across its five main galaxies, and collectively, they’ve got more than enough on offer to keep players occupied for plenty of time. Those looking for secrets and optional content, however, will also find a fair amount of it in the form of Lost Galaxy Levels.

Some of Astro Bot’s best and most creative levels are found in the Lost Galaxy, but unlocking them does take a little bit of work- which, thanks to Astro Bot’s excellent platforming, doesn’t feel like work, at the very least.
