Trophie and highscore are now fully functional. I also lowered game difficulty by changing levels layout and monsters shoot / move speed.

• tiny-tigers move and shoot slower.

• Only one killer ball in the 2nd round of the first planet ( 2 was too much )

• Infection from the the 2nd planet spiders now grow slower so you have more time to get rid of it.

• Changed the layout of planets so the first round is easier and the third still challenging.

• Fixed a bug where level down was removing wrong gift
