Hello everybody.
WARNING, THE FOLLOWING TEXT MIGHT CONTAIN SPOILERS
About the mouth thing... When the screen turns dark, you know the mouth will open and the big beam will be fired. After the mouth opens but BEFORE the beam is fired, you must shoot the face that appears behind the mouth, you might manage 2-3 hits.
HOWEVER
When you do, and if you managed to do it in the first place, the mouth will generate some creatures (delicious irony, things are going well when there are creatures after you) which you must kill. Li will be free so he will help.
THAT WAS NOT THE POINT
When the beam is prepared to be fired again, it is done A LOT faster, and I don't manage to get in for a hit and I get hit by the beam which SEEMS to deal the instant death (or just takes a lot of health) so beware. It seems you must have to attempt this kill on odd occasions, skipping turns so to speak. This is where I am now, and this is where I have died 3 times and counting (because the beam takes all my health, leaving me with no time to heal) but, it may surprise you to hear that I am absolutely delighted to have come this far, because the Creator #3 (the giant bug thing) kept crashing my game (ver. 1.0.0) but after getting 1.0.3 it works.
ONE MORE TIP
Creator form #1 and #2 are easier to kill if you have the energy shot upgrade meal, which you SHOULD use. The later forms are killed with little benefit from that.
NOW ANSWER ME THIS
While fighting Creator #2 (the headless squid/human creature) is there a way to break free from his hand grab. I managed to kill it without being grabbed, naturally, because I know not of the means to break free.
Sorry about the lengthy post, but it's better to say everything at once lest I forget it. Don't bother welcoming me to the forum, this game is SO good, that alone is enough
