Thanx for links. The Ugly Prince Duckling looks very nice, it has a very unique visual concept, I like it

Yeah, the 'death' sequence should be just like you described in Evil Twin: non-violent & a bit casual. I was thinking that maybe scene could look like this..

When cought:
1.The player surroundings are getting more red & after 1sec all but player is in high sepia color.
2.At the same time there's a zoom similar to the one we already have, zooming on the player.
3.If it's brother his crying, if it's sister she's crouching frightened.

..or something similar to this.
I believe that the part where everything is getting more red, except for players, can be achieved through use of customized shader.
