This screen shows all the information about the selected hero.
This includes:
The level-up button is highlighted when the player has enough resources to buy a new level. Once the player presses the button, the resources are removed from the player’s inventory, and a level-up animation showing the new stats appears. This action can be performed as long as the player has enough resources to buy the next level.
When the player has enough anima shards to upgrade the hero to a new star, an upgrade button is highlighted. The behavior is the same as the level-up, but the animation should be juicier.
