Choose to be green or orange. When the maze appears, the color you selected will be the one you move. To complete the level, get both of your blobs to the portal at the same time before time runs out.

If one of your blobs gets trapped, the other blob can shoot him once, releasing him. Ghosts cannot be killed, and if you touch one, it will swap your characters.

Use the arrow keys to move. Getting a key eliminates walls that have a key symbol on them. A snowflake freezes enemies. Green arrows give you extra speed. A plus sign gives you more points and a clock gives extra time.
