I don't usually go ahead and call a submission crap, but I feel this really deserves it.
I ran a search in the NG search bar for "asteroids" and was barely surprised to find that there were 276 submissions that related to asteroids. Granted some of them had nothing to do with this game, MOST of them were carbon copies of this game.
So I would say that this game has been submitted at least 200 times.
Yeah, thats bullshit. I'm already pissed off about all the cookie cutter games the portal has been crapping out since 2009 and now I have to see "people" (if they're even human and not automated bots) create accounts, and then submit a shitty carbon copy of a popular game within minutes of joining the site. Truly I'm surprised your crappy rip-off doesn't have an obnoxious ad in the beginning, considering the general population of cookie cutters tend to have those in their games so they can squandle for ad money. So maybe this is a different situation entirely, maybe I'm just going crazy over nothing.
Should I even review this? Its asteroids, thats it. The same damn game thats been flooding the portal 200 times. You could literally steal someone elses variation of it, change a single sprite or font, and submit it without consequences.
TL;DR;Too Fucking Lazy: If you're coming to this site to submit crappy generic games, then welcome to the ocean of shit.
Also: Just set your author credit as Author if you wan't everybody to know that you made everything.
