Since there did not seem to be anything constructive left in the reviews below mine (at least not at when I started writing this) I figured why not....
Great game, only thing I might suggest is the option to un-equip weapons. I found that some level one weapons, such as the shotgun and the M79 were actually worse than the default melee weapon, because the rate of fire was so god awful slow and lack of any considerable damage, I often just left them there to pile up. Which leads me to the other problem, freshly dropped items stacking on top of already dropped items. This wasn't a problem normally, unless on of those weapons that I already mentioned was on the bottom of the pile. It actually turned out to be safer to keep a good weapon and do without the medkit than to pick up a M79 and regain half my health. Anyway, I'm just wasting space now, In conclusion....
Damn good game, just hard enough to make it fun and enough funny bosses and comments to keep me entertained, keep up the good work.
