DR.TANK is a two-player puzzle game with box-pushing as its core. In the game, players will play as the strange alien doctor and his beloved artificial intelligence robot, and help each other to climb over obstacles and escape from the crisis-ridden laboratory!! In the game, the doctor can shuttle in the jelly-like dark matter blocks, but cannot move freely in the air. On the contrary, the robot cannot cross the dark matter, but can push the blocks and create a way for the doctor to escape. One of the biggest highlights of the game is the space sci-fi style art style. The effect of transparent dark matter squares is produced by shadergraph, and the effect of elasticity is given to the squares by means of the principle of mass point spring. At the same time, we also added DepthOfField, Vignette, Bloom, Tonemapping and other detailed screen post-processing and volume fog effects, coupled with the embellishment of dynamic scenes, to present the players with a magical and beautiful world of abandoned space laboratories. In addition, the completion degree of this game is extremely high, with all functions from basic playing methods to item collection to archiving. It is planned to put TapTap,4399 game box, steam and other game platforms on the shelves. This game aims to convey the valuable truth of mutual help to the author in the play. A doctor cannot escape from the laboratory without the help of a robot, and a robot cannot overcome many obstacles without the help of a doctor. Both are indispensable to each other and complement each other.
