With all the comments I see posted. This is game had the first interactive developer screen which was awesome I would like to see more of those. Specially for the ones that have like three different screens.
I looked back a bit in the comments and for me when i upgrade something to max play a level and go back to the upgrade screen the upgrade is back to 9. Dont know if I am alone in this but it seemed to merit a comment.
I dont like how there are buttons everywhere asking you to pay that and there is a glitch with explosions (they dont explode when it gets laggy might just be me though)
