Shotgun Zombies are nearly impossible to kill because they seem to *always* knock you down and have seemingly no Reload... Combine it with dogs (especially the black ones) or more Shotgun Zombies, and it's an almost instant death.
I don't like this one thing (and mind you that I'm only in the Zone 5), but it's an otherwise alright game.
@Atombender I think I have the same bug, but my map only resets the areas accessible after getting the Cyan key... All the stuff available before beating the first boss (not including the Yellow Key Guardian) is still there. The reset includes blocks of the map that can only be accessed by jumping from a post-cyan key area... Is it the same for you, or is it a complete reset?
Fun, but hand spasms become way too frequent at the katana. It would be nice to have more gloves so that it wouldn't happen. Maybe even a glove made for each weapon that would keep spasm to a minimum, i.e.; the higher weapons have lower Pain or add more gloves with higher tolerance.
As soon as I learned not to use the S move in the final battle while the opponent is over an edge, it was quite easy...
I don't know how many times I died from that damn S attack...
