Really fun adventure! It's rare that we see so much content for a jam, this was three worlds and even a final boss. All were fun to play through, and interesting things kept happening. I'm personally biased towards music, so I will always recommend having a soundtrack, even if it's taken from opengameart if making music is not your thing. That being said, the sound effects were really good, and the gameplay was both challenging and forgiving, in a nice balance. Great job!
