played your game 2, 4 layers of shields first i thought i reload them with cookies, good that you have story with voice and audio (rated 4 stars), out thought that is not started to say: red alert - when all shields was down, if you try mine go pro
Thanks for playing our game! The cookies are just triggering the raise of the temperature and the enemies attack. The bonus when an entire group of enemy is destroyed, only lower the temperature for a little bit.
