A secret some of you may have already noticed:
use emergency boost when you need instantly anytime:
When it shows the message , press "P" (Pause) and press lots of letters, then unpause, and you waste almost no time!
How about if you can interact with certain objects with mouse (toggleable on right side menu)
Like pull the reload lever on guns, spray aerosol can, release gas on gas tank, drop gasoline (or whatever is inside) from barrel, etc.
Needs some sort of tracking device that seeks for alive objects, hover and gets about 2 pixels distance from the nearest alive object.
So you could you could attach to stuff and make stuff that locks-on target, like a smart missile.
Or a turret.
Also needs real fire,flammable things, etc
