Hey, I will drop my feedback below:
I really like the sfx music and animations you have going on. However I think the card animations compete for attention with hint texts on hover and makes it harder to interpret what the card does.
I find it odd for the non-interactable titles that you use in some sections (e.g. deck selection and new round sections) to have the same visual language as the interactable buttons.
Some background movement and/or particles in the main menu would be nice.
I think this kind of mouse based game would benefit a lot with using a custom cursor. It could have interaction hints (via animations, color, etc) as well.
The approval goal tutorial arrow didn't contrast enough imo.
Hold button made me think I had to hold my click on it.
Maybe it's just me but I though at first that I could reach max tension meter with no problem and that only if I get past it would stop the round.
Having available buy buttons in red feels off.
Having currency closer to the costs of the things you have to buy would be nice.
