Nice game. When I first saw the scissors in the 'only one room' level and couldn't move them, I thought the game had broken and I couldn't progress. I fiddled with it for a while before I realized it wasn't part of the objective. I imagine it was set in place as to not misdirect the player, but I think it would've been fine to allow it. While it would've made me think I had to do something with it, the level forces you to think outside the box (heh) anyways, so a little misdirection would be fine. Also, the flower is really hard to see if it falls on the floor.
Edit: One more thing, the scissors in the wire level. Since they only cut when you click on the wire itself, if the player clicks the mouse before he points to the wire, he may assume that clicking doesn't do anything, as happened to me.
