The original thread was in French, and we all know that online translators aren't much of a help. So, I just went ahead and tried the game to find out what its all about.
In front of me was the adorable tomato, on what looks like something that resembles a hop scotch diagram, only it only has number 1s on it and a timer on the upper left corner.
Since the short but sweet How-to only says up,down,left,right, I went with my instincts and pressed any of the four directional buttons. At that the tomato inched its way forward, and after a couple of jumps it reached the checkered flag, and on cue, the star transition came into view and I was transported to the next level. I thought, easy enough. All I have to do is jump these numbered squares and reach the checkered square.
But of course, it wasn't that simple. The next levels, had different numbered squares this time. By this time I found out that the numbers represent how many times you can step on that square before it disappears, leaving you stranded.
By the third level I started developing a strategy. I was also keeping an eye on the timer, I don't want to waste time, but I also don't want to make a stupid mistake of being trigger happy on the jumps, and accidentally eliminating squares that I need. Good thing, the game gives you unlimited tries on each level.
