The scaling element was cool I like the challenge of moving the the boxes and having the scale. I did notice that when played in the browser the camera crept higher to the point it was unplayable and I couldn't see my character. I was then able to keep playing once I full screened it though. I also soft locked the game by accidentally dropping the create inside of a column so that I couldn't shoot it. The last thing that I had trouble with was figuring out that I needed to press the 'E' key before I shot each time to get the scaling to work. I thought it was a toggle in the beginning.  But I loved the style and like I said the idea was really cool. Great job! 

This game looks good but it could really use an indicator for which mode you are using and at one point the crate would not change size so I got softlocked :/
