Good, but work on making it somewhat destroyable. Like a moderate jolt to the head makes it come off or something like that. Very good textures.

Very good, Very artistic, but it needs to be destructible instead of just saying "rip" when you hit something. And what is that truck supposed to be there for, it's just a roadblock...

I wish it was interactive, like if everything had gravity and could collide with everything so you could introduce some new comet, asteroid, or planet to make everything messed up. But still really good, I like the background things! 8/10

Very very interesting and good, just try to put more in the description, and it's spelled infinitely (at least here in the US).

It also sounds like you're claiming that theory as your own, when really you're just stating it in a new way using phun.

8/10

I can't get the gun to close. But some of the misfires I've had looked cool, so I won't rate this. Make it come loaded with one shot, and have it open and close with keys so it doesn't explode at the least provocation.

Needs more streets, not an interactive vehicle. Awesome, but it's too small. 9/10

Looks: 9/10 The bullets are amazing!

Interactivity: 7/10 It needs something to shoot at, needs to be aim-able, but other then that I like doing most of it with the mouse and a little keyboard.

Complexity: 9/10 The things that are complex are hidden, after one shot you get the hang of it.

Break-ability: 10/10 rarely breaks if you're doing it right.

Overall: 9/10 The best gun I've seen, but other then that there's not much to do with it. Reloading it is fun, moderately easy, and doesn't take too long. The only problems I've had are the bullets going off or sliding out when you're putting the barrel back up. Keep working on it!

Good, but needs to be scaled down so more fits on the screen. And it'd be good if it was a little more volatile, like if adding a high gravity comet with an irregular orbit made everything out of whack.

He never said he could do better, he just said it's too hard and not stable. O.o

5 Stars isn't possible...
lol

Interesting, I guess it's a good start and good concept.
Keep working on it, try to make it less leaky. Less randomness, too. Maybe make some things interactive...
