Ah yea, I remember that now. Shame though. I woke up today with the idea of having a random plant in the game snatch you with its vines and initiate a sex scene with a plant, when you walk over it unsuspectingly that I was gonna suggest. Ah well.
As for the scenes in the game, I think there should be a menu item that lets you access unlocked scenes without any sort of text in the way, like a gallery, on the main menu before loading the game. Instead of only seeing those things at the save point.
By the way, whats this "lightweight" mode on the main screen?
I just loaded the game up again to confirm the main menu thing since I had loaded up 4 games that day trying them all. :P Another suggestion in the programming side, would be menu options for adjusting volume for different things. Music, Sound Effects, Moaning/Sexual Noises.
In my case, I'd like to set the music to 50%, Sounds to 70%, Moaning/Sex sounds to 10%. Instead there's only a mute button to mute all sounds.
