Well, for once I was able to beat one of these games on Hell mode. It's pretty rare, usually on those hard modes I give up near the middle (near the final bosses if I'm lucky). I guess after observing the enemy enough times they eventually become predictable, including the final boss. I'm just glad my arms are just sore and haven't fallen off yet.
Anyways, interesting choices of enemies to vanquish; the clown was the most interesting one. Use of a gun and able to move around and jump were excellent. Ducking has saved me countless times (along with the ability to still shoot while doing so). Overall a good game.
So nice job, keep up the good work!
