EasyGameStation is a doujin developer powered by fandom. Each of its games pay ode to the Japanese classics that came before them. Sometimes they feel like an inspired tribute (Recettear), while other times they border on being an unofficial sequel to an established franchise (Gunners Heart).
The only thing consistent in EGS' catalog, that jumps genre-to-genre, is quality. In that respect, Chantelise: A Tale of Two Sisters is no different.
