1-6

1-6 is the sixth stage in Level 1. This stage introduces keys, a mechanic that unlocks more tiles to the player.
== Structure ==
The stage consists of a rectangular ring with notches on the middle of the long faces. In addition, four platforms are bridged on the short sides with tiles that can be only unlocked by a key. Two flowers are placed on each of the long faces of the ring, and spawns can be found on the short faces. A tile containing a Stamp can be found near one of the spawns.
In the beginning of the stage, the pink key on the top of the stage is the only key accessible. Obtaining this key, in turn, gives access to the blue key on one of the platforms, and then the yellow and green key soon follow.
On the platforms where the blue and green key are located, pairs of paint rollers can be found. On the platform bridged by the tiles unlocked with the green key, a flower can be found.
