Background

In this game you play as Zhongli, a sheltered 18-year-old who lives in a large compound with his two moms, Hu Tao and Eula, who have raised him from birth. Zhongli is homeschooled by his two moms and has rarely interacted with the outside world, preferring to spend his days with his moms. Recently, Zhongli's two moms have been teaching him linear algebra and physics, with a focus on vectors. Zhongli then wakes up on a seemingly normal day but with a strange power related to his education.

Controls

Press Space to advance text (don't press anything else during dialogue or the dialogue might end early or NPCs might get a little bugged.)

Movement - WASD

Camera - Move mouse/trackpad to look around

Press E while looking at NPC (NPC should be in exact center of screen) to interact with them (Note: the game intends you to interact with NPCs in a specific order so if you interact with the wrong NPC the camera will just jump to the NPC you should've interacted with) 

Vector Control

Press right click to focus and enter aiming mode (movement in aiming mode is kind of bugged so try not to move while in aiming mode)

Press R to lock onto a Vectorable Object. You should see a white coordinate grid appear.

Aim using the mouse on the coordinate grid to aim a vector.

Press left click to set the vector.

You can set up to two vectors.

Press F to apply the vectors you have set, setting the object's velocity to the vectors.

Press C after you have set two vectors to multiply them according to the cross product. The blue vector is the x axis, and the red vector is the y axis. The cross product in this game uses the left hand rule for cross products.

Press right click to exit aiming mode and be able to move again.

Notes:
