Propagation Game

Grid-based game with refined targeting system allowing a selected cell to target only one of its adjacent cells, which then increases in value every second.

Prompt

Now I can select but I can only target myself, upon which it starts adding +1 to all adjacent cells. That's wrong. The target should be one adjacent cell only. So after selecting you should pick target cell out of the adjacent ones that it thereafter starts increasing every second.
