Nice game loop, simple and fun, well designed !
I can definitly do higher score but i have other things to do. And I killed one cops, that's a victory.
During free times i put many candy as i can under the candy bag, not too much just in case cause the game limit the number of candy you can pull off, so i keep some to be able to also drag candy from the bag. When delivry guy come, i put letters in a side and wooden planks in another side.
Then I take the gun and open the door. When it's the kid, I drop the gun and take fast a candy to give him, usually he have times to make 2 knock max, sometimes none. When it's a monster I spam shoot, cause sometimes the first shot doesn't hit, then i drag the gun at the candy pile to reload, and get ready again for the next.
Now all i have to do is not shooting the wrong guy cause with the pile of candy i can fast reload and chain the monsters if needed, like i tried in a run for the test to kill delivry guy first time then kill as cops as i can, and I killed liked 8 cops before dying.
When i've reached 216 points I had like 10 wooden plank left and used only 2.
Also if the monster come inside to rush to me, you can close the door fast and the monster will be set back to the door, so when i need to reload, the door close itself, giving me some more times.
And in my run i didn't took my times to look who's outside cause i just wanted to rush, but you can definitly play more safe at the end to make higher score.
