Some help in case anyone needs it:
- Use the arrow keys or WASD to move! (Also good for choosing where to stick a goob cube once you come into contact.)
- Space is used for jumping. (If in contact with a goob cube, it confirms cube placement.)
- Pink goob cubes move like you do and jump higher, while greys are inert.
- Goob cubes can only be moved on your person and the structure you end up creating, so be careful which ones you put on a ledge or in a pit.
