Most annoying is that you don't get to see a map of the level when you get to it (through 'next level'), so you waste one shot on reconnaissance. Going through the level select all the time shouldn't be necessary.
too easy, too short. missing the kind of useful mission details that other, better assassin games have. the warehouse is one of those missions where the bodies pile up in plain sight and noone reacts. that's kind of weak.
Interesting concept, but it's really unclear which tiles are being swapped; I kept finding tiles that i thought I had swapped back in their original positions.
Not once did I have the feeling that I was in control of what was happening. When you can get a fair ways through a game by holding down 's' and waiting for the enemies to crash into you, there's something wrong.
Looks good, plays well. Hard to judge which are stars and which are balloons as you fall. Would have been nice to watch the descent from when the parachute pops, too.
Are there instructions anywhere in-game? Calling this "strategy" is being overly charitable. You click for a while and then you're done with the tile, repeat until end.
Neat combination of puzzle (usual gems / 4-in-a-group thing) and defence. Sort of triangles-meets-zombie-rampage. The aim is really hard without a target cursor.
Like ThreeFish said -- it's an ok game. Pretty good compared to some of the others like this, and the way you order your own soldiers tactics gives it a bit of strategy. 4/5
