Perspectrip
Read full descriptionHide full description
A mind blowing puzzle game that challenges your spatial abilities. Simple shapes are spread apart in pieces floating in a 3D space, and there is a camera angle that aligns all pieces and builds each shape. The game is played by rotating the camera around to find such angles and build shapes. When shapes are built they are removed and points get scored. Perspectrip is easy to play but hard to master. Avoid piling up too many pieces or the game will be over, use all white power-ups strategically to keep on scoring, and compare your score on baKno’s Top Players list.
