We've rebalanced the game in future versions and will continue to rebalance based on content amount.
The dev team has to decide if the focus of the game Sugar Service is supposed to be the card game or the story. If its the card game, then the game seems way too repetitive and simple for how long you have to play the game. If its the story, then the card game is way too grindy and should take up less percentage of playtime .
For sure, totally get that. As more content is added, we wanna offset that by allowing said content to be accessed easier through rebalances. We're definitely on team 'story is the main focus', which is why the card game at its current stage is very simple and we totally hear you about it being less grindy.
