Postmortem of Space Crush

Release of the game:

I have released this game on the google play store here.

And was able to have saving working properly with Unity serialization, as well as Unity Ads.

However some bugs still need fixing, as the ads play after every round, regardless if they win or lose, and there is no timer to reset it so if 

you lose and watch a 30 second ad and then lose again in 2 seconds. You will get another 30 second ad, so this ruins the fun of the game.

Other thoughts or additions:

I was thinking of adding some sort of energy powerup that might have a certain radius to eliminate all aliens only in that radius, to maybe balance out the gameplay and not make it as tense near the longer waves.
