Oh I thought that was the pool he drew from. So we draw hearts, submissions, etc, to pay for these, hope they show up and ???. I don't understand where in the process actual damage is done.
I beat the first two bosses by clicking every single card then the top line until it let me add one.
each round you begin with a starter deck comprised of brain and pills. The brain is one of three 'currencies' used in the game, the others being hearts/seduction and submission. Over the course of the round, as you become more transformed your basic cards will change in the following pattern: Brain>Heart>submission. The pills are basic attack cards that you start with. The damage you deal is shown with the letters "TF" inside a pink circle.
Each turn you play cards from your hand by clicking on them, in the beginning, you will have only basic cards to play. When you play enough currency to buy a card from the line up above your hand (i.e. the rightmost card at the start costs 3 brains, if you play three brains on that turn you can click on that card to add it to your discard pile. more expensive cards from the line up have more powerful effects, they can deal more damage, let you draw more cards, give you shields which represent defense against enemy attacks and/or they can give you more power. Some theme suits that can be added or substituted before each round might come with their own unique mechanics. Suits have powered up forms that, in older versions came from playing x amount of that suit in a single turn. In the newest update i am unsure how you get them outside buying them with points earned in between rounds. Suit Power-Ups can unlock additional effects for cards of their suit, improve their effects to make them stronger, or can reduce the total cost of cards in that suit.
In order to win rounds you need to fully transform them. Each turn you deal damage to your opponent equal to the amount of 'TF' you played that turn minus their defense. Once their meter is completely filled up, you win.
