So far everything works except for sound/music toggle, and the "Go" button. Also I'm quite upset that loading the game launches a new window/tab for armorgames.
I fail to understand why self decapitation is worth anything other than ~maybe~ a quick smirk... beyond that, the grab mechanic fails far more often than it works, and even when it does work, it turns into who is more stubborn, guy pushing to go right, or guy pushing to go left. (AKA who lets go first).
Thanks for the feedback! But did you read the instructions?
"Use your arms to grab the opponent."
That's probably why you are having trouble grabbing.
"Whoever’s head hits the spikes first loses."
You might be able to decapitate to have the enemies head fall first, or if you are both falling, you could try to shoot yours onto the platform, etc..
Though it should be noted that the cabinet (code opened) you need to click on the handle after entering it. (also that the clue from the turtle is read in an M pattern)
It was fixed in the update.
