Cool concept! I think in the second level, you should make using the players as platforms a little more useful, as currently you just have to kill 2 people and use the last person as a sacrifice. The platforms are also a little buggy.
We agree! The goal of level 2 was to tell the player that all Raiders must die to successfully complete a level. I guess you probably fail this level at first because you didn't kill all the Raiders, did you?
