Post jam version

Here's some of the new additions for the post jam version



- The camera movement is more smoother
- There's a final score now
- The crate has an indicator for when there's only one smash left with it
- The speed of the zombies is no longer bugged by framerate
-  Depending on your combo counter, there will be a point bonus added to your score with every kill. This point bonus is displayed next to the combo counter
- Zombies bleed to indicate that they're about to die in the next hit
- The game gets more harder the further you get now
