Update: fix internal logic

In this update you will find some changes I made. 

First, I Fix the collition of the player when he attack.

Second, I fix some collitions on the levels (a small problem with the floating flags).

Third, I added a escalated price increase in the updates system.

Fourth, I added more static mesh in the blueprints, giving a more complete aspect. 

Thats all for now, if you have aany suggestions on what to change or add to the game, feel free to put it in the coments section.
