The hunt for F rank - Haunt the House

Recently I've been playing some flash games and I came across this game which I had loved very dearly, so I played it and it was very fun to try and achieve 30/30. But I found that it is more difficult to try getting 0/30 than it is to get perfect score and I tried searching for people who had been able to get 0/30 but found no one, even more so that the worse score anyone has done is 23+/30 so I had been trying to get 0/30 myself. I had it down to 14/30 which is something I'm proud of.

Update: got 17 kills this time. unfortunately I had no video of it, only a screenshot. but it proves that it is theoretically possible to get 30 kills. -28/10/23
