I made many improvements in particle system of the game, putting to work the process of particles and sound when enemies die.
Also several improvements were made in the base particles (when receiving damage) and also in the selection of process objects (there are still problems in the selection of towers to display the context menu, but for the trees the selection process is working correctly) .
One method that has been adjusted for the generation of enemies now with the possibility to switch the points of birth and also the way that the enemy will follow. So the game is not as linear and requires more strategy since enemies can be generated from different points in the the same time.
