Kernis games are awesome, they are the only ones I know of outside Illusions stuff where you can move around and interact with girls/androids like this. Nothing against renpy or rpgm but this is seriously raising the bar for indie H games.
Unfortunately they both have one big flaw during the 3d scenes, the zoom function takes over the mousewheel and you lose the ability to scroll the text. These need an alternate control option. Also for some reason doing anything in that second pirate base lags the hell out of my system. Shame because I'd love to see MC take it over, I mean everyone gets a base except him?
I'd also love to see the arousal meter collars come back from the first game, as well as them tracking where on the island the girl is. With the nature of the experiment this should be data gathered from the test subjects anyway.
