Heh, I just did it 172 frames faster:

It's not worth watching, if you just saw the previous version. First, I noticed a little mistake and edited it out. Then the movie desynched, because a destroyed bush did not respawn as it had done before, so I accidentally found out that bushes have a random chance of respawning. I then managed to manipulate another bush to not respawn, so that's a total of 2 less knife swings, 14 frames each. I also managed to make the rain not start near the end of the movie, which saved about 2 seconds. I lost 1 frame manipulating the movements of the bats, so there is a chance that the movie is not perfect yet. Anyway, I feel a bit clumsy with VBA and I don't have ideas for more improvements, so feel free to replace the submission file with this one.
Sorry again for improving a movie shortly after submitting it. I did wait a few months before submitting, but it did not help. :)
