Oh that's really wise. I love your puzzles, they are really creative.
Game is really well made, however I lacked music (if you missed time you could always try Ecrett, it's very simple).
Graphics are minimalistic and pretty. You could add just little particles while moving, it might give some magic touch to it.
While being in this reveal box, there should be a possibility to jump again so you leave it. As sometimes you wanted to just have a short glance.
Anyway, great submission :)
