I uploaded an updated version (playable above).
The glitching was a bit annoying, I did notice that as well. Apparently I completely forgot that collisions don't work well with tweens and spent an embarrassing amount of time fixing it.
I also had a version with the "free movement" and included that movement. I never did think of the free trailer, but I did incorporate it and it does seem much better now. Kind of like car pinball.
I added
- cop cars that come and shoot at you, you have to bounce cars into them to get rid of them.
- health. If the cabin gets hit by a bullet or a car, you lose health. Also, cars that leave the screen that havent been hit by you or other cars make you lose health.
- free movement between lanes
- the ability to spin the trailer out using the "z" or "x" buttons.
