Good. One of your better escapes. Nearly everything is logical (one or two keys appear out of nowhere when unrelated actions are performed... happen in a lot of escape game, but still always seems disorienting.) The gameplay is satisfying. I didn't really get stuck anywhere... the player only has to figure out where to use the proper items and codes, rather than puzzling out bizarre sequences. Also, the fact that the cursor turns into a hand whenever you're over an interactive item prevents the adventure from turning into a pixel hunt. That's one mechanic you've been using for a while, and I really appreciate it. I did have to TAB to find one spot, but that was my oversight.
Simple, colorful graphics. I liked the animation on the cat, which looked pretty sleek. The music track is pleasant.
I only have one issue: I never actually found the order for the marbles, but the first attempt I made was correct. Did I happen to get lucky, or is there no specific order?
