A unique four-dimensional puzzle, but please do not expect to solve it easily. The game consists of rolling a golden sphere to each surface of a hypercube. This is done by touching a door to pass through which in turn rotates the tesseract four dimensionally and brings the sphere into a new room. Passing through a series of rooms strategically will put the sphere on the walls and ceilings of rooms it has previously been in. The goal is to reach every wall, floor and ceiling of every room.

Verdict
The clearest difference is price: Tesseract! at Free against Kotoro's $0.99. Kotoro's advantage is update cadence (every 6 weeks vs every 66 months) and rating (4.7 vs 4.4). On review sentiment, ads, in-app purchases and device support there is nothing between them.
