small fixes plus new platform support

the original game used to only be playable on webgl, but as i was making small changes to the game i was like "huh, why not".

the game can now be played on windows, linux, and even android devices. pretty cool.

in terms of small updates, i changed the song since the initial song was something that i picked last minute and was the closest thing i could imagine to what would be playing in the background for this type of game.

also the game is a bit harder now with some added screen shake xd.
