I think you created a good base for a game. You're just missing an element or two more to make it fun and engaging. In particular, it's not clear whether there's a fail state, which is awkward in a game that's keeping score.
The visuals are pretty good. I like the overall look of everything. However, it is a bit confusing to have the chicks look so dark in such bright lighting.
I think the gameplay's relation to skill is not quite there. As it is now, the game seems to have one exact state that is optimal at all times, with no meaningful choice on how to play. While it's not the only way to fix this, I think allowing things to pass either in the middle of the lifts or on top of them would give the ability to consider multiple items at once and thus allow better multi-tasking, without having to rely on the items sometimes falling through the top. From there the rate of things coming could be adjusted in various ways on the fly while still being fair to the player.
Lastly, I notice a bug in the collisions. The egg and the pumpkin both move with the next lift if it is moved while they're on the crack, but the chicks will stay in the same position while even moving clear off the previous surface.
