Challenging, but not in the way I intended.
It's not bad, but here's what usually happens:
"WTF? Where do I go? I can't tell where to go with such a limited view. This is retarded!"
"That fucking golden needle keeps killing me, even though it never touches me! In fact, most of the enemies don't even hit me, yet I keep getting killed. This buggy entity bullshit is retarded!"
"My shots just pass through the enemy! What gives? He can just graze and kill me, but I have to hit dead center, and limited to only 4 directions? This is retarded!"
"The enemy is positioned in just a way where I can't hit it, and if I try to, it'll probably kill me anyway. In fact, I can't even see when an enemy attacks me before I can dodge it. This is retarded!"
"The same bosses, over and over? Just grouped up differently? This is repetitive. No, wait... that's retarded."
But really, the game itself is fun. It's hard. It's fast-paced. But PLEASE fix those fucking entities. I'd rather go "AWWW! Damn, I died again. Man this game is hard, but fun!", but instead I'm saying "IT DIDN'T EVEN TOUCH ME! GODDAMNIT!"
Then there was one instance...
"Aww, sweet, got to the boss without a single death."
*Cat walks in front of monitor, stops, looks at me*
*Hears plummeting sound, game over*
"FFFFFFFFFFFUUUUUUUUUUUUUU-"
