Alright, my 2 cents.
I had so much fun playing this, no joke. It was fun as hell, specially once i got the gatling laser and then mowed stuff down faster than it spawned... *sigh* good times.
BUT:
Dude, what the HELL is with us not being able to actually win? Like, if you're gonna make me get to the Doom Machine and fight it for a tedious 5-6mins cos it won't die then make me fail, at least gimme a proper reason.
And the other thing is guns. Why oh why did you not simply make it a choice before each level which gun to use out of the ones you've already bought? Cos this way i was pretty much afraid to buy anything else after i got the gatling laser out of fear that i'd not be able to reselect it. And i didn't wanna risk my ticket to the end of the game just for curiosity's sake.
I liked the random between-game awards, was funny, and the fact i played thru the whole thing means i didnt hate it, but without those two things....would've gotten a 10 from me probably.
P.S.:
Oh, and why cant we move to the left?? O.o
