Well... it's helpful to write the game's controls in the description, because rotating camera by holding right mouse button is rather cryptic and user unfriendly. And I couldn't figure out how to swing the sword, which should probably be the the most easily accessible command (if it's implemented already), e.g. left mouse click. Sometimes while going into the gaps between buildings, your movement animations can turn themselves off, so you just float around until you jump. The graphics are of course great, but you should perhaps alter the scale – now the main character is just as tall as a door (should be like ± ¾) or as a castle gate with a portcullis (which should be way bigger). The knight on the street doesn't have a collider, you can pass right through him. Also, since there are no shadows, the main character seems to "float" over the ground instead of walking. And assuming the transparent grid in the corner is supposed to be an inventory, part of it appears off screen (speaking of which, perhaps it'd be good idea to add a fullscreen switch).
If it's your short promo game, it can't just look good. It has to be fun to play, even if for a mere couple of minutes. Now, there's a pretty game, with cryptic camera control and bare minimum of interactivity. Anyway, I assume this isn't the final version, so good luck getting there, and good luck with your application.
