You can play OrThought with either the [WASD] keys for movement and [QERF] to manipulate the camera, or with the [arrow] and [/*-+] keys, which serve the same functions. You want to get to the exit in each level, represented helpfully by a big E block. Every time you fail, whether it be by falling off the map or breaking beneath the mighty mass of a marauding moose, you'll have to start over from the beginning of the level. If you get stuck, you can reset the level at the top of the screen from the menu bar. OrThought does not feature an autosave function, so remember to save your game on each level and before you quit.
There is a sense here that OrThought is almost, almost, absolutely fantastic. But just because it falls shy of achieving that doesn't mean it isn't enjoyable. There is a staggering amount of ambition behind this game, from the wonderful complexity of some of the puzzles to the simple yet charming 3D presentation itself. There are teleportation pads, ice blocks, water, keys, robots and much more to discover, each with their own set of rules and behaviours. It makes what would otherwise be a typical sokoban puzzle into something really special.
Unfortunately, OrThought's biggest enemy is its own interface. The controls can be frustrating when you first start off, which may turn off people looking for a more laid-back experience. With no Undo feature, any mistakes you make can force you to restart the level. Considering how quickly the game begins flooding you with new elements, it's too easy to make a misstep. If you can stick with it, OrThought offers a lot of challenging puzzles and clever gameplay. As a first effort, it makes its share of mistakes, but it also does a lot of things right, and puzzle fans who give this one a chance may just find something to love.
