you can but is hard. I don't remember but I think the every npc has one combination and use use it all the time. If you loose you can beat remembering what he used the last time.
I mean it's not like we're paying the game and supporting the makers or anything, that's what I use this site for, shitty sex games that either aren't worth paying for, and even if they are, aren't worth appearing on my credit card statement
In my experience they picked the same things everything mostly, I wanted to see all the scenes first so I tried losing on purpose, sadly I won and didn't get to see a couple scenes, so just try top bottom order and there are a couple you'll win, and if you lose the match but won the first round, remember that since they neraly always pick the same ones, the truly frustrating part about the game is that theres no scene viewer at the end, so even though I spent 30 minutes to win the game it was for nothing since theres nothing to unlock, and although the video is great I'm 90% sure they just ripped it from an actual hentai animation of bulma, it would make sense, who would put so much effort into making that great animation and then no effort whatsoever on the game itself, makes more sense that they stole the footage from somewhere
