Had fun, the gameplay and levels are original! I didn't mind the slippery movement per se, it added charm. But it was a bit too difficult to quickly move the barrels around in the later levels so I had to give up. The restart taking too long and having to spam click to attack was also a bit frustrating. Finally, I see no reason for having to press E to pick up the arm. Minor critiques aside, a very solid entry. Great job and keep it up!
