Really fun clicker that I hope you'll decide to polish up more for the christmas season, I think it has the potential to be a really cool small game! What's working really well already is the overall gameloop and the satisfaction of upgrades. The concept and slowly increasing chaos feel fun!
Background music would have elevated the experience a lot, as would a few more sound effects for unwrapping and presisng upgrade buttons.
I stopped at 180 parcels - I think at first the way the gifts on the floor move towards the hole on nudging feels quite good and fun, and it's nice that it always moves in the right direction. But once the game gets busier, the gifts get in each others way and get stuck a bit, and I found myself spending most of my time trying to wrangle them to the centre with little control over their movement. I think fixing that somehow would remove a potential frustration point!
Great job, it plays quite well!
