In the current build, a lot of assets have different pixel scales which makes the game look like a mashup of unrelated assets. Art-wise your game would've looked a lot more cohesive if you would've gone with a uniform pixel scaling.
The gameplay is fairly complex and while fun and interesting and I love that you went with a digital board game I think a concept like this may hinder you in ratings due to the complexity of the game. People do not spend too much time learning games and if mechanics are too complex you may run the risk of people dropping the game.
You have fairly large cards for placing upgrades but it only counts as an upgrade if you place the dice in the specific dice spot. I assumed I would get the upgrade by just placing the dice on the upgrade card. I would recommend adding a feature where dices get magnetized to the correct spot if they are placed anywhere on the upgrade card.
You could also add a scale and a flash to numbers whenever a number is updated to draw attention to the player that something has changed. The numbers are an important aspects so it's important to make sure players are aware when the change.
