I updated the webversion and added the desktop version, the webversion is too buggy because of unity and chrome.
there are plenty of unity games I played that worked correctly. this one crashes after you beat the boss, funny ending actually. everything collapsed but I got there by pure power of will, and I didn't even use the sword attack or dodge roll.
the problem is the next scene, I'm going to remove it from this "tutorial-demo" sorry. there is a bug with a custom shader grass and unity web.
