For a first game this isn't that bad, especially not one made in a week. It has focused gameplay and a story, which is more than I can say for my first ever game.
That said, what i feel this game really lacks is proper feedback to your actions, from simple things like hit effects to knowing when you could act or when your actions have cooled down.
Then there were the chaos effets that happened in the last battle, which I'm not sure is a thing that is automatic, or was activated via Chaos Explosion. While I don't mind getting a random effect each turn (and I appreciate the sheer amount of effects), due to the lack of feedback I had no idea what each thing did. Like, what does "chaotic softening" even mean?
