Psychoban is a nicely-designed 3D puzzle game for the Mac. In it, you control a patient in a psychiatric hospital who is instructed by his doctor to complete a set of puzzles to test the results of a surgery he has just undergone. There are different game modes available. The first one is a story mode, in which you play level after level while reading bits and pieces of a plot narrated by your doctor and other hospital staff. The second mode is Temple Challenge. Instead of playing in a hospital setting, the puzzles are in temples. The first levels are more complicated than the first hospital ones, which tells me that overall, the Temple Challenge mode is considerably harder than the story mode. Lastly, there is a mode called Buddy Box Challenge. It is unlocked until you complete the story mode.
The puzzles consist of one or more blocks that you have to drag around to place on top of markers on the ground. To move them, you can click on them and select one of the possible moves. Unlike similar block puzzles, this one is done in 3D, so you can also pile blocks to complete levels. The only thing you should keep in mind is that when a block is placed next to one of the corners of the screen, you won't be able to move it from that edge.
Psychoban can be very challenging and that is something that I always like in a game. The game levels are designed quite well and I like the work done with the dialogs, which can be funny at times.
