Looking for game help, please

I was sitting, so I came up with the idea to play one good game. The only problem is that I played it 5-6 years ago, and even more probably. I quite don't remember, I would and could find, but it is not very popular. In General, all caring guys give the description:
The game itself is quite complex in terms of physics and awkward opponents, specially made to control the character was quite difficult. The game is 2D. The main character is Celik with a brain in a jar instead of a head. For levels we need to dig the earth, to the grandmother to buy the good soldier and go to war, instead of the hero it is possible to switch and control between the soldiers, which we buy. In this game you can travel between planets, sort of. The level ends with a loss in that case, if our Celik with a jar instead of a head just simply kill opponents. The game is single player only salanova, only hardcore.
This is the maximum description that I could give (it's pretty bad remember). I hope there are many who also managed to play this a good thing and tells the name, I will be extremely grateful :*
