Good work on the art style and audio. Although the skill floor of the game seems quite high. Having a few more levels that ease you into the swing of things might be beneficial. I like your use of the environment. Especially in your initial tutorial text and of course sing the exploding barrels against the bosses was quite fun. And as a minor nitpick some of the animations seemed slightly choppy. Overall, the game is very fun and engaging. Nice work :)
