It took me a bit to realize that you could pick the box up into the air. Once that click the whole world opened up. This reminds me a lot of braid. Good work
The game seems fun, but the when it's the right moment text blocks the player from seeing half the screen. I believe it is the third text box. Therefore I often kept running into the wall because I could not see.
I like the mechanics. It almost feels like a puzzle game. It might be better if you had unlimited tries to search out the level. I see a lot of potential in the idea.
