If you hate the game because it's not much fun to be maimed and left for dead by forces beyond your control instead of being able to shoot down five enemies with a single bullet and take down a helicopter with a bow and arrow, then you've got the point of the game completely.
It's subpar and lazy for not letting you advance text and letting you crawl all the way off the screen (it's not like I'm giving it 5 stars), but it doesn't really need to be fancy. Now if he were to make a game where you were maimed and had to crawl your way to a MASH unit to survive with obstacles that are tough to overcome, trying not to black out from a concussion or exsanguinate or such, that'd be 5 stars, even if you still got killed half the time by forces beyond your control just to get the message across.
