Limny

The game play is simple - the goal is to get 20 red stakes to the yellow door before the screen is completely filled with water

For that, you move the black cursor and can create or destroy a block in the labyrinth.
As they are released, the stakes are listed at the bottom of the screen.
The first level is always identical from one part to the other, but from the second level, each part is different.

There is no game over, as soon as a level is finished (victory or defeat), we go to the next one.
