Ah, the gameplay is meant to be challenging, glad it was quite enjoyable, hehe...
Hmm... Its kinda like facing a slow and not so intelligent you wielding a double barreled shotgun, when you meet those pigcops, i guess they can be tough (and to the point of frustration in skill 3/4), but still doable.
Well, i dont know what else to say, but did you know the advanced AI is pretty much enforced on almost every monster? :P
Hmm... The boss room is a bit small, but i didnt want to make an ugly oversized room either, not to mention, currently, the pal 21 bosses have a damn small hitbox.
Altrough for me i found him too easy at first, made his attacks a bit stronger. You will find hiding behind the boxes (and crouching) to be effective to reduce damage, i guess.
Not to mention his attacks will also make it hit itself sometimes, shoot the rpg a few times in its face and he'll go down. :P
Hmm... Unfortunately, i dont think i'm going to change anything, i suppose every map has its tiny flaws and will not suit everyone's taste fully.
