Good not great.
It's very attractive, the different items and the tactics associated with them are well thought out. Your success in this game is way too random though. Three times in a row, I rotated a row/column and the resulting row/column was all skulls. That's right, THREE times in a row. As long as there is the possibility for this to happen, a human player making the best possible moves cannot guarantee victory, and this is the problem I have with your game.
Suggestions to fix this:
1) Make it impossible to rotate to three of the same object, OR
2) Make it so that if you do rotate to three of the same object, the row you just rotated is not counted in any matches on that move. Maybe make it so that that row has "jet lag" so if you rotate an adjacent row/column, then the row of stars/skulls that you uncovered the previous move resolves.
Those are just a couple of suggestions which would eliminate the unfairness in this game. Very good concept. Attractive flash. -gc
