Graphics could be better, even with your style. The poster below me said something about music, but i didn't hear anything, so i guess you removed it?
The puzzle were kinda okay, however i got stock at some point. I planted the carrot and seeds and then...i tried everything, i tried combining everything, linking an object with everything on the screen, nothing. So if it is not a bug, i figure a walkthrough would be nice somewhere.
But my actual problem with this game was...the story. A bear(why a bear?) getting tired and sleeping on the road...really? really now? And then a truck comes, and he somehow knows he has to wake up, but can't and hast to solve his dream to somehow get up?
You could have done something better with this whole dream scenario. Also the drawings of the OC's were annoying as they served no purpose except for...no, nothing at all, as we don't even know your friends nor your friends oc's or whatsoever.
If you want to include your friends characters, you could make a game about THOSE instead.
