wow, the game looks great. The movement/animations/alerts felt really cool. the sound effects are awesome.
*I liked the idea a lot so I might have gone too far below*
Far-end clipping felt like a pro and con: it made the current decision matter more but also losing the level because of that felt unfair.
the mouse can be changed to some other icon or making a popup when it hovers over the switch might be great. but it felt fine after the first level.
SCORING/DEATH METER
the math model of scoring felt hard. I felt it can be toned down to 10's to make it look easier or maybe a comparative model like
a child is twice important than a person
old person is half important than a person
a zombie/killer might add to score or nullify the deaths of those on that track
hinting to make it easy
a moving meter that shows the better decision just seconds after you move on a track but not the entire solution so increase or decrease the weight of following decision.
the end:D:D
