I like the idea of swapping roles between being the shooter and the duck, but I think the rounds go on for a bit too long. Maybe something like 30 seconds would be better? For the shooting part it felt like an alright length but it feels kind of long when you're just running from AI gunfire.
I also liked the visuals; good choice of assets there, but the gunshot sound is really grainy on my end and gets annoying pretty fast. But overall it was still fun!
