This is Deception LLC, a set of six user-made levels for Beret. NOTE: This level set contains signs, so for the best possible experience, play in Beret v. 1.2.1 (or later).
Here it is - Deception LLC's first release candidate! These puzzles are designed by award-winning DROD architect George Wanfried, and you won't want to miss them!
This level set features six levels, each trickier than the last. There are simple puzzles, complicated puzzles, and puzzles that make you wonder just how they're possible, until you finally figure them out. There's a good mix, and both the puzzle structure and the level structure are superb.
If you're looking for an alternative to Beret's main game, this may well be it.
