I love the Babel Tower. I played it since I found it a few years ago and I had lots of boosts by clicking "restart" a million times. A few days ago, the game was upgraded and I was pissed that I lost all of my boosts, science etc.
I was looking for these upgrade "codes" I had never heard about and complained about floors, boosts, science, etc all lost that I had lost and immediately got a reply from the Dev saying he will try to fix it. And what do you know?? :)))) I came back this morning and my boosts/golden bricks were returned! Although, I am not able to see if my science points were returned or not, I am happy! Give these games a try, it's fun!
