I don't know if I can do edits while jam is going, so I guess I cannot add control texts now. The red wall is the highest building on the level, so you need to cilmb a wall by holding W key.
The game was supposed to have 3D complex shapes to make the use of 3D environment, but I didn't have the time. To do it. As for colors, they actually do change by using left and right arrow keys. Then you press Enter to select the next cube. The whole gameplay mechanic was tested couple of times so it should work.
I used 3D graphics extension, so most of the 3d rendering routines comes from it, but camera control and mouse control are made by myself with a bit of stack overflow :)
К сожалению, мы вообще ничего сделать не успели кроме рендера и физики. Было рабочее освещение, но и оно сломалось, так что да, весь геймплей в том что можно упасть в пропасть.
