Diamco

Description
Diamco is a puzzle game in which the players must arrange the letters scattered around the level into the target word(s), built from left to right or top to bottom.
Letters can be moved in any of the four cardinal directions but will only stop when coming in contact with another letter or a wall. Letters can be selected either by clicking on them with the mouse or with the Tab key (or Shift + Tab to cycle backwards) and moved with either the mouse or the arrow keys.
A limited version of the game was distributed as shareware and contained only 6 levels, compared to 60 for the registered version.
