So I found a glitch. Well two actually. The first is that I got the achievement for killing the second boss when I died early on in our fight. The second is a bit weird. On my second playthrough, the game glitched out just before getting to the second boss. I defeated all enemies, but the boss arrival bar wouldn't fill up. After a little while, there were a bunch of explosions. The explosions lasted probably about 20 seconds before the second boss was defeated and the next wave came (I didn't even fire a single shot at the boss). After each wave, there would be a few seconds of silence before an explosion signaled the start of a new round. And no enemies were even attacking me. The third boss died immediately too.
Well dang. Picked up a key on a pedestal and it went halfway off the right side of my screen in the inventory. Now I'm stuck forever in this one room with the key in my hand. I can't put it down and I can't leave the room. That sucks.
No mute button (that I could find) and laggy to the point where I can't play it (I thought my computer could handle medium, but apparently not). I even turned everything to false and still couldn't play. 1/5 from me.
Stuck on level 19. I keep having just one egg left. And sometimes you have to do the same thing several times to get a decent result. Not a very good level.
Why can't I join the game? I know their codes and have the mirror set up! What else could I possibly do? I've spoken to everyone like a million times now!
Did you give money to Bullock? Bribe him and then talk to him again about Mentzen :)
If you're still stuck, don't forget there is a walkthrough linked in description!
It slows *you* down.
