Aha! That Japanese website romanizes it as
Alien Crush and not
Alien Crash. Looks like the U.S. release was the correct title after all.
Hmm, before I watched the trailer, the game looked too much like a human's inner body with pointy teeth in various spots but after I watched the trailer, it really does have that Alien feel to it.
I was expecting something more Ridley Scott'ish but this looks fine.
