It's present stomping time!

OK, here's a small Xmas platformer we put together recently. It's simple, hope u like it! Merry Xmas to all!
Best played as a popup. If game lags, set graphics quality to Low!
The Xmas presents are rebelling! Help Santa get the problem under control and jump on the presents before they doom the Earth!
Every time you jump on an xmas present a new present is added to the tree. Your objective is to fill the Christmas tree at the top left with presents. The ultimate goal is to fill the final diamond tree.
Can you get through all the levels?
Try not to land on spikes or get trapped or pushed off the screen - that will cost you hit points.
Look out for bonuses!
