Good but...
I found a pretty major bug that really sucks lol... If you accidently double tap down when you go through a door, sometimes you just fall and die...then fall and die...then fall and die... I lost all 5 of my lives this way at the 2nd mission. Oh and did you know that when you die for the last time by falling, you can still shoot as much as you want? it's kinda funny lol. Either way it was a good game... Seen the same exact thing many times but not bad.
