Anyone who has crashes after resetting earth: It seems to be crashing when the available purchase counts going up too quickly. First upgrade everything, then buy everything you can by 100s, go back upgrading, buy everything again by 100s, now it would be safe to switch to MAX.
This is an awesome game. My son loved it. However he couldn't go further than the first few levels. It would be extremely cool if there were more very easy levels, specially for those who's just learning programming. A "programming school" level pack, maybe? Or a level editor for parents :))) This could be an excellent teaching tool!
I don't know... It was much better a few versions before. It seems you are trying to make it funky, but you just make the UI overcomplicated. Hire a professional, if you want a bit more complex interface. It was VERY GOOD a few months back.
