Game updated with feedback from the presentation!

We had the first presentation of the game yesterday to our teachers and class mates.

Some points were highlighted during the presentation and many of them have been implemented in this latest version.

Updates from the latest version:

- Allies now only move when clicked on the gameplay area or when enemies are too close to them

- Fixed balance of waves

- Fixed some timer and display issues

- Boss no longer collides with other enemies, so they can go through with ease.

- Player can go through allies;

- When imune from damage after getting hit, player can go through enemies too (prevents from getting stuck)
