i see where you're going with this map, but it's just too damn grueling. the chainguns are effective enemies, but there's constant little things that put me like a deer into headlights with them; for example a lot of the mines impede movement on already limited running space. also their reach is far too omniscient. they're always pinning you down whenever you reach a particularly hard stretch of mines or tricky tile formation, which is no fun.

i think you need to open this map up a little bit; give the player a little more freedom!
