The interface is typical of point-and-click games: Use the mouse to collect objects, move about the ruins, and solve puzzles. The puzzles are engaging but fairly easy, with a lot of finding the code here that unlocks the door there. The mood of the game is perhaps more important than the difficulty. With well-rendered visuals, appropriate sound effects, and some interesting environments, Psionic does a good job of creating a sense of discovery, though with a heaping helping of hoary pulp-adventure cliches as well. Beware of some gratuitous jump scares as well.
In addition to puzzling, the scavenger hunt aspect of the game is also very important. While you can complete the game without collecting and photographing every item you should, you will not discover the mysteries of Tombscape 2 unless you do so.
Tombscape 2 is short, simple and not wholly original, but it is a well-made and evocative bit of point-and-click adventuring. It may also provide some measure of distraction before the inexorable tide of Armageddon casts the temporal realm into oblivion. Best get to the adventure then, while there is still time.
