A fun "X-Com style" game, with turn based tactics. For the most part: I found it to be well done with decent graphics.
I did have some glitches when advancing, and the tendency for enemy units to show up with your last movement was annoying, especially when combined with the ground dropping behind. (If the ground is collapsing, why bother sending a team in to kill the prisoners before they are killed by the collapse?)
Another minor annoyance is the way the animation for breathing looks like the guy is going to hurl, or is bowing in a respectful manner to someone off screen. (Except that he also bends his knees to breath?) Maybe add some animation moving his arms instead of making him look like he needs to find a bathroom?
Game play wise: I would have liked to have leveled up the characters instead of unlocking higher level versions of them as I level up.
Overall this was pretty well done, and a bit of fun to be had from a flash game.
