Shattered Legacy

I had troubles with first 2 launchings of this game on my PC: I couldn't proceed further than clouds in main menu, though I heard the game sounds. At its 1st launch the game has started to install some Microsoft program for it without my permission, I think it's weird... And a bit inappropriate. But ok, then I played like 2-3 times. The game seems to have quite nice graphics. It's sokoban type of games [in ancient Egypt/Greece setting]. Controls [so far] are just WSAD to go/push the crates in front of you, and "Space" to interact with some objects [hit crates or ballistae]. I was a little uncomfortable without the ability to rotate the screen, because it is not always clear where the passage is in the wall [when I could see the level from only one angle]. I played something like 10 levels, and each level was dedicated 1 new in-game feature. So, the game has good tutorial, with no rush. Loading screens before each levels have detailed description to each new in-game objects in that levels. First puzzles were easy, of course. But still quite good. The "campaign" is not linear - sometimes you can choose from 4 different levels where you want to proceed. Game description says that the levels have "replayable" value, but I don't think so: I wouldn't beat these same puzzles in second time. My FPS was only 9-10 in this game, which is terrible: each move was like the "slow-mo"... Futhermore, when I wanted to play today I got black screen... I tried to re-launch the game 2-3 times, it was poinless [black screen and game was not responding to me], so I'll just delete this game now... It's too unpolished in my opinion. "Free" is the max fair price for it...
