This game is great despite of some bugs, i don't know if you are doing all the arts alone, it is really great, however it would be great to have matching arts with the main character's hair colour for example, if you have the time and will to anyway.
I would love to see more story or quests after the main planet, a space station or even more alien races/planets with unique quests such as slavery market or cassino brothels, also a pregnancy system to make the game more challenging. More locations on the planet would be nice too, would be a interesting if we could return to Earth as a type of ending too.
