Interesting concept, but the levels are way too easy except for the last few. It also feels like having multiple bears to drop is unnecessary (except for the level with the moving dropper, maybe you could make more levels like that!) 

The visuals are nice, although the truck doesn't really fit in with everything else. The music is nice and peaceful!

One more thing I'd like to add is that I didn't realize some of the platforms could be rotated at first. A short tutorial or some instructions would be nice!

(I hope I'm not being too harsh, I'm just trying to help!)
