The concept so far is interesting. I really like how a "free sex pass" (literally talking) didn't turn into women just being rolling down the MC's feet. I know it's a very early stage of the game so it's kinda hard giving proper advice. Maybe, for a tad of more realism, make the timer a tad longer (like 15-20 minutes, half of that time goes away just by saying hello and finding a place). If I had an advice to give, keep it real, don't turn the MC into a super dude womanizer just because he becomes more confident. The interaction Diana felt so so real, I kept thinking "yeah this is how it'd probably go down on a scenario like this". Can't wait to see more of that :)
