I can't seem to kill the second boss (where you re-enable the power to the subway) in v1.11. This seems kind of silly since I have all 3 weapons at max power. I do some damage to him but he always kills me first. Any tips?

If he appears, try to avoid bones which he pukes, then jump and shoot him with spreading gun (shotgun or alt-fire of pistol) before he dissapears. Walk around all time and use Shield, so it's the better chance to survive while bones come from ceiling. And about Shield, it's good when before fight durability is full and you have focused magic orb for shield regen.
You can also see GentleRaven's walkthrough in Youtube and follow his strategy.

Okay I have beaten that boss, but now it seems that I am officially stuck at another position.

I am at the Marsh. I cannot pass the blue smoke because it kills me. However, if I go back to where I came from, there is an obstacle that I cannot pass from this direction - the house where the guy tells you that he had to kill his whole family, twice. The passage is blocked and I cannot jump high enough to go back whence I came. Also, to the very left of that stage is a ledge that I cannot reach (too high). So what do I do now?

The posts have been split from the bugs and glitches topic, because that thread is not for general discussion and only for reports of bugs.

You can attach your save file in this thread so we can take a look at your problem.

Well at this point I do believe it's a bug. Okay, here is my gg2save1.dat file. Wait, if I want to attach it the forum says "The extension dat is not allowed." Huh?

I actually have managed to pass the blue smoke now - after getting my health up to the full 12 points - but there is not actually much at the right end of this stage. Just one monster, that's pretty much it.

Screenshots (hosted at ImageShack):

1.) This is where I entered the area I am stuck in. I can pass that house coming from the right going to the left, but not the other way round (cannot jump high enough).


2.) This is the very left end of that stage. Again, I cannot jump high enough to advance here.


3.) This is the stage with the blue smoke, the door to the left is locked so I cannot pass here.


4.) This is the very right end of that area, after having passed the blue smoke. However there is no exit nor anything to pick up here.

About 1st and 2nd image: You should more practice with double jump. Don't jump in mid-air too quickly after first jump
3. You should get a silver key to pass through silver doors. This item will you receive very late, so don't care about it for now.
4. Because you haven't fifth gun. After getting it, here should be Alt-fire orb for this gun.

Okay... it seems I have finally got the knack of double-jumping. Seriously though, there should be a tutorial for dumb people like me.
