Very fun game! The world switching mechanic is similar to something I did years ago (don't look it up it's incomplete and horrendous), but the barrel moving mechanic was a very nice touch as well!
The game itself was very on theme and very fun! Visuals/audio are fantastic as well! Only feedback is the player control script being a bit too sensitive. That last portion I hopped over that barrel about 15 times and almost raged.
