There is no 3rd collectable key-block in Desert level 3-4. Level has only 2 sections. There is only 1 block to collect in each (2 total).

subj^ P.S. Really, why not also to tag it as "grand Strategy" ?

I completed the game 100% but only have 3 achievements: 1) The Rage 2) 25% 3) 50% I also saw the ending but got no achievement for it. From the list, I think there's 1 for that.

I try to start the game, it doesn't start. what could be the problem? all games start.
