In 1D (One Dimension, like 2D and 3D) pulses are coming from each side in a one-dimensional world and it is up to you to cancel them out as you move back and forth. When the avatar is black it can cancel blue pulses and when it is green it can cancel red pulses. With using only one dimension, and two buttons, 1D is a simple and fun game, which is also surprisingly complex. ***** - “This game is surprisingly fun. I will have to say that this game could have given pong a run for it’s money.” -Dan Staley Features ========================== ● Simple controls ● 3 different game modes with movie based tutorials ● Great if you have a just a minute or full hour to play ● High score tracking for each game mode ● Quick startup time
