This is a good idea and I think you've got the beginnings of something really cool here! I like the physics of the barrel and navigating the level with it to the chest. It took me a second to get the idea, but once I did I was able to play the other levels. Congratulations on finishing your first game! It's SO much work but super rewarding! You should be proud :) Keep it up, either with this game or a new one!
