Avoid common Color Block Jam locked-door mistakes, including moving the key too soon, blocking its approach, and confusing setup with completion.

What is the first key mistake?

Moving the key because it is visible without checking the door route. Trace the key to its matching destination and preserve the lane it must cross.

What is the second mistake?

Filling the door approach with an ordinary block. A matching move elsewhere can still be wrong when it occupies the only key lane or staging space.

What is the completion mistake?

Treating a key or chain animation as the end of the dependency. Confirm that the intended route is usable and identify the next destination before continuing.
