First things first. Something I always tell Unity devs, who don't make web builds. Make web builds. More people will play your game (or in this case cutscene).
Now, about the cutscene. Nice to see some proper unity camera usage! And animations! Better yet- voice acting!
Two things confused me though. First- one of the guys was a cop? There's sorcerer, knight, a dragon, some undead creature, and a cop. Why a cop? I couldn't tell :)
The other one is- I didn't feel the connection between the clock and the action. I mean- I got the characters, I saw what they wanted to do, but I didn't know what was the significance of the clock.
