You want to pay for a demo?

To see things positively it's nice to see ambitious games ported on Android. This one is very good, with excellent achievement (although gameplay is a bit too dirigiste) but that does not excuse that the game was divided into 4 chapters on Android and you do buy here that the first chapter, you will pay about 3.5 per extra episode to finally obtain a complete game as it was sold on other platforms.
Game kit, Pay demo, there are several ways of judging the method. It's as if we did pay the shareware version of Doom limited to the first episode. This is a different era.
