Wanted to rate this game 5 stars because:
1) It gives a totally new puzzle experience comparing to other newgrounds puzzle games.
2) It's Challenging! Like a game of chess you got to think like 3 - 4 moves ahead.
3) The so far looking seemless FB connection (got no experience with clay.io before so time will tell)
4) And personal to me, it's pretty addicting!
One downside, the game wil make the level win or fail sometimes, when there still is a coin (wich adds bullets specifically) on the table, so at that point, you're NOT out of moves, but the game thinks you are. I remove half a star for this.
