But fun is no increase for the third part

I liked the third part right, the fourth part now is more of a disappointment for me. While the game is still fun, but I find it a pity that the private mode was removed from the third part, and also the level system has deteriorated. In my opinion, even the multiplayer now often loses the connection, so you then have to finish the level alone, and then, of course, has no chance.
If the errors are corrected in multiplayer and added the private mode, there are 5 stars from me.
