As a first release, it's not bad, but it had a "loot box" mentality.
For now the lore is just, you end up in this bar, you need to go up fighing girls at cards and win.
After a battle if you win you gain 5 gold, if you lose 1. With 5 gold you can buy a card pack or if you input a code, a specific card. Off course card codes are for patreon only. If you had all cards of one specific character you gain his stories.
The gameplay is simple, i wish for a key to end turn quickly and a better tutorial.
All cards are more kinky contents than sex scene.
Overall i had fun, this first release is not bad.
