This is really good. The mechanics are fun and fairly intuitive.
Rewind isn't a true rewind since it is possible for the back and forth to be in the other state. But frankly I like that way because you can get weird interactions
7.4 is maybe a repeat of another level? The layout is the same. might be different peices/restrictions.
I wanted to keep playing past the 32 levels.
Top notch. Seriously.
