I think there is a good idea here. As far as clicker games go this one is pretty engaging as it has some rhythm elements. I will look forward to its development.
My biggest issue with the game is how multipliers locks us into certain girls and positions. In one run I got an S card, then pulled two A cards I hadn't unlocked yet, but I didn't want to switch to them because they would give me less multipliers.
To fix this you can do one of two things:
- Even if you switch to different girls/position, always use the highest multiplier you unlocked during that run.
- Calculate multipliers for everything you unlocked during a run. So in the beginning your position multiplier is 1x, then when you unlock another position it becomes 2x, when you unlock a 3rd one it becomes 3x etc.
Another confusing choice is stage selections. Why are we fucking in a volcanic cave or on top of a column? The first stage, which is a nice hotel room, is the best. Different stages is a great idea but I would prefer a pool or a club restroom before really weird ones.
As for some future ideas you can implement alternative themed modes. For example, a BDSM mode where instead of sex positions you unlock different implements like whip, paddle etc.
