Interesting game with solid mechanics and well thought out rules. Props for that! I spent about 4 hours on it yesterday and today (which shows how much I enjoyed it) and I noted a few things that could use a bit of tweaking to improve the experience, at least from my POV.
Right now the Story mode is slightly too hard and I think there are a couple of reasons for that but it all boils down to:
TF Score of 100 is too low, it should be at least double that (maybe more) and the transformation thresholds where the buy stacks change should be accordingly further apart. The moment you "built" a usable deck with INT cards, you already get mostly Sex cards. After some learning curve you can manage that change, but that means you have to quickly buy up Sex Cards and will VERY rarely be able to buy (and less use) any really high level INT cards, later high Sex cards and so on - which will bite you in the ass during the Boss fights (more about them later). The switch from Sex decks to D/s Deck is even worse as the opponent by then will have stacked on TF cards that you will speed through the 50-75 TF stage so quickly that you will have real problems to make another switch, especially as you will still get a lot of (now useless) INT cards and so on.
Right now the only working strategy I found is to stack up on "Survival Cards" how I call them, cards that give Armor and Card draws. This mostly comes at the price of Offensive (TF) cards and high value cards (2 Scientific Advisors or Paranoia and One Spreadheet are worth MUCH more in "Battle" than "Triumph of the Mind" or what the 8 point INT card is called), which is a bit one-dimensional and does not make use of the tactical potential in the game.
The other tactic I could see (and that I will try out now) is to go for Sex/Bdsm Decks from the get go and try to "nuke" the opponent before he gets too dangerous TF wise. But again, that is a bit restricting in my opinion.
This also makes the "Perks" you can buy mostly useless and better avoided imo. The Boni are nice but not worth the loss of actual time in "Battle" as far as I am concerned.
Then come the Boss Fights... geez. Too much. The mechanics are ok but without a reset of the TF score, you either are super duper lucky and come out of a Battle with 30ish or so TF score or you can just reload. That might be different if you had actually loaded up on high value cards, but right now I was lucky to get hands that give me somewhat around 10 offense and 5 defense every second draw and that is not cutting it really. Here you could REALLY use those high value cards that you mostly did not want or could not buy if you wanted to win the normal battle before.
Lastly, too much is still dependant on pure luck of the draw. If you had a couple of bad hands in the beginning, you are actually better of to reload a save. Thats ok in the first couple of fights, but later you should get some bonus for getting this far, card wise, so that a bit of tactical acumen is rewarded, like with an extra card slot or maybe a "wallet" with some one use cards and so on.
I know that is what the Perks are meant for, but that does not work imo, not with their TF cost at the current 100 TF Budget. And I also know that the unlockable Perks like "Leet Hacker" also already go in that direction, but firstly they are a bit random to unlock as you have little control over your decks and secondly they would need a lot more play time to prove effective (see above).
Gee, what a wall of text, I better wrap this up. My suggestions would be:
Either Increase the TF Threshold from the start or at least add something to it for every conquered enemy (Like maybe 20 to TF per round?) Make it cost something (as a Perk) if you think, but the option would be needed.
Add more cards that can lower the TF score (or a couple of "TF immunity for a round" cards) and add them earlier in the card stacks. So far I always get the one I saw late in the sex/ early in the BDSM stages when I have no chance in hell to pay their high INT price.
Add a mechanic to "dump" TF points before a Boss fight to give the player a fighting chance (maybe in exchange for the highest value cards?)
Anyway, thanks for a good time so far and lots of luck with your game!
