Hah what a meme, had to try it just to see more of the trainwreck that is Im-dal-young. Spoiler: It's same trainwreck as always and f*** this game for ruining decent gameplay 4/5 for the gameplay design dropped to a 2 for the pain of interacting with this engine.
This is a 99% focused gameplay review, I do really not care for the story so I skipped it(looked similar to the manhwa). The art is consistent and quite good live2D, the english seems decent but has typo errors (like heroine misspelled as hiroine). H-scenes presented with panel boxes like a manga.
So now gameplay. Honestly I like it and its got a bit of choice complexity. If you've played boardgame dominion then playstyle may be familiar with a neat twist.
You start heroine chapters with a basic deck and build it through their subchapters and it all culminates in a final battle where you use the stat cards to boost for a kinda rock-paper-scizor style showdown where your ability will be based on how high you got the parameteres during the card phase.
You start the turn with 1 action and by default draw 5 cards from your deck to you end and by end of the turn you will discard all cards not played.
The deck consists of 2 types of cards, action and stat card. You can play as many stat cards as you want to either counter the randomly chosen negative NPC cards presented or to unlock a positive NPC card. The stat cards not played will instead boost one of three parameteres needed to pass the subchapter requirement and give you some gold to spend, primarily on buying new cards but there are other uses as well.
Action cards cost 1 action to play and perform meta effects like [draw 2 cards], [+2 actions], [+1 action and draw 3 but boost every stat not 0 on NPC cards by 1], [+2 action, +3 card and add a worthless 0 stat card to your deck], [gain 700 gold], [pay 500 gold to permanently remove a card from the deck] and more. There are more action cards added to the game as you progress the Heroine chapters at least for the first 2 of them with the 2nd chapters being more complex than the ones in chapter 1. Can't answer about chapter 3 since I didn't get that far due to the reason listed sometime later in review
And now finally time to answer the important question which is the entirety of why I find this game neat. How do you gain more cards? The answer is the [open shop] action card. Yes that's right. Expanding your deck will take up one of your highly important resources to play the essential action cards and is done midgameplay. And thus you get into some interesting choices between purposefully failing the early but easy NPC cards to get gold to go shop while its easy and fairly painless or try to squeeze in a purchase lategame when the shop card is a liability for your draws and may cause you to fail the NPC card check.
The final mechanic is the forced link button that lets you pick one of 4 options, +1 action, +1 draw, +500 gold OR "Reduce every NPC card stat by 1" and then it adds a "forced link" card to you hand. If you let this card stay in hand until the end-of-turn-discard it will add a random amount 15-25 to the mental breakdown gauge. At 100 breakdown you instantly lose the game and need to restart from the latest subchapter with a consolation boon (+2 to any one parameter or +300 gold).
So the game needs you to manage a balance between buying strong cards so you minimize played stat cards to gain gold, having enough enough +action and +draw so you don't get action starved (a full hand of +2draw but only 1 action to play with is some literal garbage), spending actions and gold midgame to both expand and reduce the deck to improve quality and consistency. I would call this a kinda compelling gameplay loop and I enjoy it.
So why do I hate this game with a passion just one normally does with any Im-dal-young creation after you get over the art? BECAUSE NOONE PLAYTESTED FOR MORE THAN THE INTRO SCREEN BECAUSE THESE UNSKIPPABLE ANIMATIONS ON EVERY CARD PLAYED ARE SO ANNOYING I WANNA STRANGLE SOMETHING. yes, the gameplay goes at like 20% the speed you could play it at and I feel I need to get cheatengine for it's speedhack due to how slow this is. I coulda done this gameplay in around 40minutes probably, now it took 2 hours.
In addition you have no idea how severe the penalties of a NPC card are until you've suffered them. If it says "-morale/-gold" you have no idea how bad it is untill you've suffered it and let me tell you, -7/-680 gold IS A PRETTY DAMN STEEP PRICE WHEN YOU DON'T KNOW WHAT YOU'RE PAYING FOR.
Edit: Now finished, I can confirm Ch3 unlocks even more action cards [draw cards until you draw 2 action cards] and a equivalent for the stat cards. I didn't get a chance to use either because my deck was already perfect and let me max the parameters by turn 24. Adding anything woulda made the deck worse, i even removed the shop card from the deck. And I wont lie. it was highly satisfying to do 10k dmg and oneshot them in the combat phase
