I finally finished the game. Good ending with a twist. Bug Zilla was easily defeated with alien gun( $ 5000), the Firefighter to prevent drowsiness) and scientist(+ 10 dmg).
5/5.
For levels with the fire-spewing power, especially in 'The Crux', hold the space bar until you finish the level while you are spewing so that you don't burn the blocks up and die.
The ending was amzing and truly is a look into the future of what humanity will become like. The endings.....he put up his middle finger and laughed in the ending upon the destruction of the world. XD
