GH: Earth and Sky Deluxe

The letters GH in the title of this game stands for"Girl Hunter" but despite such kawai theme it is going to be quiet serious looking game taking place in a world of futire combining elements from fantasy, science fiction and even steampunk! In other words - you better see everything that this game has to offer by yourself. Th egameplay is also going to be as complex as teh definition of game genre since it includes elements of strategy, planning and even turn-based battle tactics! It might take some time fo ryou to understand the overall control scheme but on the other side you better not play this game if you are looing for quick and simple adventure - here you will be dealing with three dozens of regular damsels and three legendary damsels so there is a lot of work to do.

Spacegirlz Returns

Hot looking chick in the pink colored armor may be the last line of defence of this spaceship that is being under attack of the xenobits right now. And the fact that they are using the new pheromons to affect the protectors of the ship is going to make this mission even harder to complete - not only the main heorine will have to fight against the hordes of enemies but she will also have to fight against her own sexual excitement! The only option to win this battle is to break through the lines of enemies and reach the control post to send the alarm signal to other defenders. Will our main heorine be capable to do that or will she fall the victim of the desire to get the most strong and long orgasm? Looks like this is up to the player to decide!
