My best Score: 2027.8
The tutorial button didn't work for me, but I think some note on the UI could have just said, "Press Space to spin and again to change direction."
Bounce is the way to go. Walk between two trees and/or stones.
I don't feel like changing directions is very useful so just having arrow keys to move is enough and the rotation can happen automatically. It would also remove the need for a tutorial.
Great unique game play and simple enough controls.
Map generation is weird but works.
Scoring is not clear. I suppose you get more points for faster swings.
Otherwise, fantastic art style. Much like Castle Crashers, which I loved. Thanks for making a great game!
