А-GA / アーが

You have three beauties (red, green, blue - a little girl, a busty aunt and a "little girl") who travel on a spaceship and perform tasks. There are unknown monsters and large-scale space battles, villainous bisenenes and ghosts of the past, unexpected rescues and innocent victims.
The rapidly unfolding plot and the pornography mixed with it do not allow you to detach from the screen. The campaign can be completed in five to six hours, and links to the hottest scenes are added to the "Extras" section.
Levels are broken into tiny pieces. The head is often completed by the boss. The menu is exited by F1, not by Escape. The adjacent F2 button turns on the View Mode, a semi-free camera that can be rotated and zoomed in. In breaks, the girls gather on the ship, get the errand from "daddy" and get ready for the next operation - you can study the dossier of the characters and chat with the girls.
