The art was simple and sweet, colour-wise. Since it was a candy factory, I have expected the sweets to look ... well, sweet and lovely and mouth-watering, but they look only plainly drawn.
Background music used in the game was cute, with some sound effects when you trigger key items.
Like all Escape-the-Room games, all you need is the left-button of the mouse. In addition, there was absolutely no lag for my computer to play this game, and I did not find any glitches in it - though [spoiler alert!] I only knew that the Black Key was hidden near the clipboard's head when I clicked the *specific corner* of the paper, which was frustrating because I had thought the paper was one item, including that corner itself [end of spoiler].
I do have one bone to pick; you can actually edit the text/comment written whenever you try to interact with things. Try defaulting it. It just seems very ... unpolished if I can mess around with the game (looked like an open Beta/demo version).
Art: 4 stars
Sound: 4 stars
Controls: 5 stars
Gameplay: 3.5 stars (gets somewhat dull and not very challenging)
