This game oozes charm! Love both the sound design and the character models. One suggestion I might have is to add some more choices during combat. While there's a lot of strategy in which upgrade to choose, once you are in a battle (where you spend most of the game) the only factor to consider is which enemy to attack. It also falls into a common pitfall for random-based attacks that sometimes you keep getting back rolls and can't do anything about it, ending a good run. A common remedy is the ability to tweak your luck in a pinch, such as the chance to once per battle roll again, which could add a bit of depth to the combat
