Arrow keys and space. Only attack works.
Play Evanescent now! http://scratch.mit.edu/projects/19252844/ This is an unused battle system for Evanescent I made back in the planning stages. As you can see, things were very different. You can only use the arrow keys in this, no WASD. If anyone wants to try and use this themselves, feel free, but you'll have to add to it (as it's unfinished) and please don't use my bad graphics!
