Toki Tori 2+ (Steam)

Toki Tori 2+ is a Metroidvania style puzzle adventure. There are no tutorials, there's no hand-holding, no-one tells you what to do in Toki Tori 2+. The fun is in exploring and overcoming the obstacles of the lush forest island on your own merit. But what's up with that black goo? It's threatening your home world! Your goal is to get to the core of the corruption and save the island!
