The 19th century explorer, the tombs, the ambient pentatonic soundtrack, the treasure marking a completed puzzle, and the lovely composite old-time photographs accompanying each area add charm to the game and do nothing to impede the flow of this pure puzzler.
Rarely if ever exceeding 7x7 tiles, these puzzles are incredibly tight. The basic mechanic involves pushing crates onto colored switches to open correspondingly colored gates, with the goal of pushing a crate onto the rooms treasure tile. There are four areas, each new area introducing an additional 18 puzzles with a new mechanic, introduced with an elegant, wordless tutorial. None of these mechanics break the Sokoban feel - multi-switch gates, one-degree-of-freedom rolling crates and grooved tiles.
All the puzzles are bite-sized, and many of them are exceedingly clever. If you get stuck, you can avail yourself of the highly unobtrusive, limited-use hint system, but I suggest you move on and return to the puzzle later.
A great game! I look forward to Timor Nigmetzianovs next masterpiece.
