Really neat concept, it seems there's lots of abilities, but the control scheme was really confusing me all the way through, leading me mostly to hitting random buttons hoping they'd do something useful.
I had a lot of trouble getting to the guard and then it seemed I kept knocking him out and getting knocked out at the same time so I'm not sure how I was supposed to handle that safely.
The art was great! I think maybe some input prompts or suggestions to tell the player how to do things initially would go a long way, I kept having to exit fullscreen to review the controls.
