Why you hide the attack menu ?

It's very profitable because beagle boy has his own generator and without limit. I'm very happy with this new feature.

I'm a little disapointed for the +3 speed upgrade for 20 coins. It last only 2 days, it's pretty short.
The +200 capacty last 4 days. Both upgrade should last 4 days.

After the bough of the +3 speed, it cannot change the generator type. We have to do before the bought ?
