I remember when this came in :)
I thought you did a pretty good job with the paintbrush style. I for one know what a pain in the butt that style can be. I would have liked to see a couple scenes maybe where the truck is speeding down the road but other than that, a nice short.
I think your style is developing quite nicely and you should keep at it.
The sound effects are right on. Perhaps some twangy coountry music in the background is needed, music would set a nice tone for sure.
No violence here.
Not much for interactivity here. You should really consider adding a nice logo in your opening credits. You did add a start and replay button. Those are nice touches.
Good in fact, great humor. I got a great chuckle out of it personally.
Keep up the good work.
