Played this immediately after the "Deep Sleep Trilogy" and was slightly less enamoured with the premise. Decent enough puzzles but the ability to do something wrong without knowing you'd made a mistake until the end of the game leaves a somewhat bitter taste. The first game of the trilogy is short enough that having to replay it is no big deal but later entries have plenty of useless items/tasks that mainly serve to confuse the player or cause a "Bad Ending" state.
Charming little point and click games. The core twist (that rather than a locked room you’re trying lock other things out of your room) works great for the first in the trilogy, and then continues to pay dividends for future installments. Don’t Escape 2 and 3 offer “escape” as an option, but hammers home an idea that this is a selfish idea when it often involves screwing over others. Just a solid hour or two of puzzles! Gotta love it!
