Today I implemented a feature which had planned from the beginning of the game. It is a freezing process of the towers.
Certain types of enemies when they die will release a gas that freezes the towers around them.
This increases the difficulty of the game and causes the player's strategies once again are very well thought out.
The towers are frozen for a certain time (10 seconds during my tests), and with a different color (see the image that some towers are with green color). I will still work on particles to signal that the tower was frozen and indicate what is "happening".
