Pretty boring. Just fixed some minor bugs and made some quality of life changes.

Most prominent changes:

1. New health U.I. features and SFX.
2. Shop looks a bit uglier to make the equip system clearer.
3. It's now possible to use soda/grenades/landmines while firing gun.
4. Bombs now explode after 8 seconds, rather than 15.
5. Landmines can no longer be used infinitely and are in now the correct render layer.
6. You can't enter the car when you're dead anymore.
7. The final boss will no longer spawn in with 1HP.

If anybody's reading this, please comment any other bugs or design flaws you'd like to see fixed. Thanks.
