Really cool game, but there is a major bug at the point where you fight the air ship. If you die, when you load back in the ship does not respawn. There is no way to continue if you are killed. Just a heads up.
Shit. Guess I broke that fixing another bug :) Will release a fix today. (You can always backtrack to the previous checkpoint to re-trigger the heli, it's on the last stairway.) Thank you man!
