i love how you wrote the story of how the game was made in the "secret", and i personally prefer this kind of philosophy games over action games, sadly its hard to find some which are as good as this one 5/5
i have just replayed the game, and when i get to the old mans story.... its so... sad? but good? its so true...
a bug: if you right click in the corner, and drag out the mouse, you are invincible until the green cannon comes, at that time you should have pressed on the kongregate site (not inside game window!) and then move the mouse into the screen, and after the green cannon and the worm, do the same thing and BAM badge achieved :)
