Semisphere is a puzzle game which requires quite a lot of concentration and coordination. The concept of the game requires you to control two orbs, one with the left control stick (on the left hand side of the screen) and one with the right control stick (on the right side of the screen)
The screen is split down the middle and ‘guards’ are placed on the map with the typical cone field of view. If you get seen by one, your orb will get sent back to the beginning. Your aim is to get both orbs to a goal which is mirrored on both sides.
This all sounds simple at first, but it quickly escalates. You can use items which are placed around the screen to distract guards so you can sneak around them, in later levels you can create mini portals to temporary appear on the other side of the screen and then distract the guards on the other side. Later levels see you jumping sides (so you may have to control the orb on the left side of the screen with your right stick) and forcing guards to the other side.
Semispheres does have a good learning curve however, every level has a few stages which introduce a new icon, so you never feel like you don’t know what you are doing. I sometimes had to stop and think, just to work things out before coordinating my eyes to my hand movements.
Semispheres is not a game for the easily frustrated, but it is rewarding when you figure a puzzle out that you have been stuck on for a while.
