Do the weapons with no special benefit from the special upgrade in any way? If not then you should probably make it unbuyable, I bought it by accident a few times then thought its a waste.
I think you should add some thing that would notify you when a rare item drops somewhere where you can't see (Something like the danger thingies when enemies are coming) Because it's pretty annoying losing a lot of items because the enemies die far away and by the time you scroll all over the place item disappears :p
Why the hell are you people complaining about the height of the window? Even if it wasn't so huge the whole game would have to fit somewhere else, either by making tons of tabs to click instead of scrolling or some other way... there's no actual difference other than extra 2 seconds to get to the comments where you see over 9000 posts of "0mfgz teh window too big, 1/5" Also to those who complain about it: Why don't you try making a game yourselves and see if you can make a better one?
Possibly a bug: When you restart the level using R your score doesn't decrease... You can just collect stuff and press R then collect them again and keep farming score that way.
So I thought the name looks fishy, This kind of games are usually called boxhead something.
Clicked the link, It opened the real site, the game is actually called boxhead the nightmare.
Inb4 stolen game, flagged.
Most of the items have facebook icon next to them, I suppose you can only get them on facebook? If so I will rate 3/5, but ill continue playing for now and see if they're unlockable later somehow.
Have five, buddy!)
