Diablo is a classic action RPG game series developed by Blizzard Entertainment in 1996. Its name came from Spanish, means devil, demon. In 2000, Diablo II appeared on the market; in 2001, Diablo II: Lord of Destruction was released; and in 2012, Diablo III went public (AppNee, of course, has no ability to provide its offline version).

As is known to all, these retro + pixel styles of small indie games are vogue for the moment. Crea's design and gameplay are similar with Terraria, Starbound or Planet Centauri, all of which have high playability. Yet Crea has its own difference and lightspot ('Key Features' lists part of them).
