Only played this for a short while, completing fiver levels and attempting to complete a sixth; so, may add more information (if there are more levels) if I get time to explore further into the game.

The developer's intro does say it's a short game.

Truck & Police:

In Brief:
Truck & Police is a 2D top-down driving game. The settings menu allows you to toggle between full and windowed mode. There are five graphic quality settings. These do not create a clearer image if you select the higher modes, all they do is add levels of shading/shadows to the game. You can see the difference between the lowest and highest settings via the second and third images. The second image is set to the lowest graphic setting, the third to the highest setting. The highest resolution supported is 1920 x 1080, with lots of different resolutions down to 640 x480; (most monitors a decade or newer probably don't support the lowest resolution).

The red indicator in the bottom right of the screen is your NOX indicator; (i.e., nitrous oxide or more correctly dinitrogen oxide [N2O] or dinitrogen monoxide ). When exhausted it will slowly refill.

The game includes brief story boards describing various characters such as Jack, Peter, James and the police officer George interspersed with gameplay levels. For example, Jack is a truck driver, he wants to join a truck drivers' demonstration, but has to try and get to where the demonstration is taking place before the police on his tail catches him. If he crashes or go too slow the police will catch up and arrest you. If this happens, which, it undoubtably will initially, because the route you are forced to take has broken down vehicles and slow-moving traffic, that gets in your way. If caught, you'll start from the beginning of the route and try again. If you make it to the truck drivers blockade you win the stage/level.

Each stage is introduced by a story board. The second stage covers the story of Peter who is a member of a racist group. To prove to his peers that he's a genuine white supremacist he wishes to participate in demonstrations, to do this he has to travel a particular route to where the first demonstration is being held. Again, you have to avoid being caught by the police and attempt to get to the place where the demonstrations are taking place. If you succeed, you again unlock the next stage. Following Peter is the drug addict James, then you get to place the police officer George in at least three scenarios. I've not completed the third of Georges scenarios where you have to catch the second of two vehicles; so, cannot say if there are further levels to play. If I get time later today, I'll see if I can catch the vehicle and see if there are more levels to beat.

If you take a break from the game, be sure to use the continue button when resuming. If you click on the new game button, it will wipe all your progress.

Controls:

W or ↑ = Forward Movement
A or ← = Left Turn
S or ↓ = Brake & Reverse
D or → = Right Turn
Space = Nitro
P or Esc = Pause (doesn't work while in menus or storyboard)
F1 = Go to main menu while in pause
F2 = Quit while in pause

A controller can be used to drive your vehicle with the left stick and NOX can be used while using the stick by pressing the Y button. NOX won't fire if the vehicle isn't moving. The controller does not work on any of the menus or storyboard pages.

Conclusion:
The game is okay for a brief dip into during a break from more involved AAA or high-end indie arcade games or serious brain teasing games, or during a coffee/tea break.

Personally, I found the game vaguely entertaining for the first few levels; however, I found there was little to keep me glued to the game, because every level was basically the same apart from the story board for each level having a different theme, as well as slight changes in the background colour and you got a different vehicle. The police car was the most memorable and using the NOX; unfortunately, I couldn't grab a screen capture while using the NOX because my fingers didn't stretch to the third key needed to take the capture. By the fifth stage, and after three or four failed attempts at catching the second of the two vehicles I gave up in frustration. I kept crashing or slowed down significantly when overshooting the road, though I did manage to catch up to one of the two vehicles; plus, it was fast approaching 4.30am and I needed to retire as I had to get up at 6.30am to wake both my kids up for work as their alarm clocks never wake them up (really).

Suggestions to avoid crashing:
Most of my crashes occurred after making a turn. The natural road line you would take following a bend usually results in a flatbed truck stopped just out of sight from the bend, and usually placed across part of the road or you may find slow-moving vehicles that cause you to crash into these stationary trucks. If you can force yourself to move to the opposite side of the road after taking a bend, you're more likely to avoid stopped or slow-moving traffic. The vehicles that are likely to obstruct you are placed quite craftily to cause you to slow or stop when manoeuvring around left or right bends. Also, avoid using NOX near bends as you're likely to go off road. Offroad movement is slower and sometimes you may get stuck temporarily.

Notes on Security
I scanned a zipped copy of the installed game using Virus Total and it found zero hits from 63 antimalware engines. You can see a scan of today's installed game HERE
