A partially finished game, designed to get a handle on how to render at 60fps in canvas.
The meter at the top changes depending on whether you prefer to jump or prefer to hit the bad guys. Jumping makes you better at jumping but worse at fighting, and vice-versa. Eventually this will make a difference.
Vaguely inspired by http://games.adultswim.com/robot-unicorn-attack-heavy-metal-twitchy-online-game.html. Should have three different bits of background music, all with the same underlying beat, so they can be faded up and down on one another seamlessly; if you're in the middle of the meter, you get some fairly boring music; if you're on the jumping side (you jump a lot, and hav therefore got powerful at it) the music will be airy, floaty, but still metal -- Stratovarius sort of thing. If you're on the fighty side, the music should be heavy power metal stuff -- Teutonic knights thundering out of the fog brandishing steel, Manowar sort of thing.
