A fun little piece!
Very fun - got over 22k on my first try...yippee! ^-^ Here are the techniques I used - who knows, it might help those who are having difficulty. =)
Art: Make one long continuous stroke between two opposite corners - either the top left and bottom right or the top right and bottom left. Either way, do that as fast as you can.
Programming: Umm...mash buttons. I'm a fast typer, so I just typed gibberish as fast as I could. XD Home-row power!
Music: I have a pen tablet, so this is kind of a workaround - I used that plus my laptop's trackpad buttons - got well over 8k on that alone.
Great game, as I mentioned earlier - reminds me of other games without the repetitiveness or tiring nature. I've always had a thing for simulators, and this one is just funny as heck. Thumbs up!
