This is an interesting concept. Flinging around the sword is fun, but it felt like my A and D keys were inverted, as if they should have been rotating the other direction. It may be because I was trying to rotate the blade of the sword, rather than the hilt, and the orientation for the buttons is based off of the hilt.
There was one confusing part at the lava area where I touched some lava and died, but I had touched lava to get there so I don't know how I could have known that this lava would kill me.
Overall though it was a good submission with a consistent art style, unique platforming, and a unique concept. Good job
