i am level 21 and i cant even survive in the 3rd map. i couldnt survive in the 2nd map until i was level 14. that is bullcrap. i am only gaining .2% every kill. my rating goes down from the initial 5/5 to 3/5.
This game sums of life better than any words. Easy at first and care free, and starts becoming increasing difficult and tangled. But it is beautiful all the while.
