This is a really fun rougelike that is best experienced on mobile. The concept of using actual die to roll your moves is really clever and is explored thoroughly through the various classes, enemy types, and items you'll experience. A major gripe I have with the game is how the upgrade classes are not linked in any way to the current classes of your characters. This can lead to some frustrating scenarios where you turn down crucial character upgrades in the late game because they don't gel with how you've built your character/team. One potential solution could be to group classes into archetypes and restrict the possible character upgrades to classes of the archetype to which they already belong. Then, allowing for a class reroll (also with dice) at the beginning of the game could be a fun way to keep the randomness of the current class system but allow for a bit more strategy.
