This game looks insane!
Love this definition!
Does it have an "old fart with slow reactions" mode :p
He he... no sorry, it's just as insane as you said - actually, even more: the chaos the mid/advanced levels bring has yet to be revealed (and experienced)

A Mac version would be nice too 
Sorry, but no other ports are planned (see post above yours).
But it should work fine through Wine - give the demo a try: if it works, the game works as well.
