Achieve Puzzle Completion Condition Detection Condition by manipulating objects, solving mazes, avoiding & evading hazards, or handling whatever maniacal constructions your puzzle designer had in mind. Not only does everything appear three dimensional, everything in this puzzle is three-dimensional, which somehow managed to set this game apart from everything else in its genre (at least so far as Eketek knows).
This is the new and greatly improved version of its predecessor, OrThought (released back in 2009). I learned a lot of things and have improved everything.
Also, if you enjoy this, consider supporting Eketek, so Eketek can improve it yet more! Buy the complete version (for $15.00) and get lots of extra puzzles, access to the puzzle editor + sharing, and twice as much music, then build ridiculously frustrating, possibly impossible puzzles, and post them on my forum: http://orthot.eketech.com
The general 'TLDR' rule: Arrow keys or WASD to move; Left-click & drag to rotate the view; Mouse-wheel action to zoom in & out.
