It's a non-functional "kill x game" with little to no redeeming qualities. So you shoot two squirrels and then no target appears for the 2nd level and then the game calls you an idiot for being "too slow." That was terrible, leaving out the animal violence thing.
Edit: Though there was no target you can still hit the squirrel. Still since the next version is just this but more, there isn't really a point to this being on the portal besides the joke of the titles.
