Boxes based on previous levels (rotate, is empty, etc.) counts your steps using your previous solution. So, a rotate actually counts as 3 steps instead of 1. A non-optimized "is empty" would make it impossible to get genius score in later levels (namely, 13 and 17). Should really have a notice on this.
I think the save problem has to do with browsers crashing... For some reasons the save every minute for me was just fine, but when my computer crashed (dorm power failure), the progress went back to about 2 hours ago.
Got all platinum except "disabled", only 287 on my best score :( I don't think EMP counts for that, and that's the hard point(flak cannon may help, but it's always destructed on 1/3 way of whole game in my case).
The screen vibrates too hard after 80,000. Still give 5/5 for it's thrilling XD
