The ability to grab multiple objects makes the game very painful. I think it's in room 4 where we have multiple platforms and we have to transport a box from the beginning that the game starts feeling very hard. I loved the mechanic, as some have mentioned, having a way to only select one object or at least allow for intentional grabbing instead of "if it's in the circle, it's getting moved" could balance the game.
Apart from this, I enjoyed it very much
