Whell I'm spanish I not defend the creator of that game
In the blog they say that game are finalist of art futura
that if the proffessinal recognition to his art

and for me, I played games in xbox360, Pc , wii ... and to many not have that quality of art. the textures are great

Probably they added more effects over that base
but for me that are a better work of many of other professional games sold in diferent plataform
