If you cannot see the title when you start push B to turn the background white,b the brightness effect does not work on some browsers, such as safari. This game still has a lot of glitches. Consider this a spoiler for the full game, but you won't find the boss level yet, not in the level select anyway. I'm just saving this in case my laptop breaks on me
I highly recommend downloading this game, it runs poorly on the online browser you can also use phosphorus here, but the pixilation effects go away and it must be used in full screen http://phosphorus.github.io/#55632260
