Thanks for the feedback! Short answer is I ran out of time to reduce the friction for onboarding a new player and other items. This game is inspired by nodebuster which has a similar mechanic of your attack being reflected back at you for a certain amount of damage. While you could in theory just dodge until the boss, it will stop you from progressing very far as you need to farm materials to upgrade or will not be able to beat later levels.
Hope to increase the polish in future rounds.
