There should be an indicator of the amount of "INVINCIBILITY" you have left. I hate to try to run into spiders to kill them, only to find out I was 1 second short..
No matter how big your planet is, it can NEVER "eat" the Sun. Could be frustrating if you had a giant behemoth that gravity didnt have much affect on crash into the Sun
When you buy the tank, please note that whenever a german is near it, and the tank gun fires... there is a chance the shell will somehow land on the tank that fired the shell. So be careful when placing the tank near a bunch of other expensive stuff. They could all be gone in seconds.
I would love to see "Dual wields" - lets say, you pick up a magnum, then another one appears, you pick it up, and u get 2 magnums that can be fired at the same time. Double the destruction.
DON'T TOUCH IT, IT BURNS!
