The key to beat the rounds is having powerful cards. Each card has a different click strength. To beat all five rounds, you'll want a card with at least x4 strength. An x3 strength card can also work, but you'll need to land critical clicks frequently.
Hey dev, I have a couple of notes from the point of view of a player.
First: I think you should make it impossible to reduce your multiplier.
Once you gain a certain level of multiplier from a card, it should be locked in until you pull a better one or reach the maximum.
Right now the feature to swap positions during a run is basically pointless because you'll always only want to keep using the highest-value position you've unlocked.
Likewise there's no reason to ever swap to a girl or outfit that isn't either a new unlock, or better or equal value than the one you've got active.
This reduces the variety of gameplay outside gallery mode by a lot and makes it feel more boring than it needs to. Locking in your highest gained multiplier would be a simple fix.
Regarding release schedules, I'll just say that while I get that you want to keep dropping content as often as possible to maintain an active image, I at least would rather receive a finished girl with all outfits less often than this current drip-feed approach, but maybe that's just me.
