DON'T WANT SPOILERS? STAY OUT OF THE COMMENTS! If you're teleporting outside of the box... your computer is lagging. Try playing the game on this website: http://phosphorus.github.io/ It should eliminate the lag. Side effect is it may remove the music. Scroll down for the game controls: Control the player with the arrow keys (hold Z to slow down). In RED mode, you can move the player in all directions. In BLUE mode, the player moves like in a platformer. "Might" make this into an actual boss fight someday... "M" to mute out all game sounds. The music doesn't loop because I highly doubt anyone can survive three minutes of this thing; try to prove me wrong. ;D EDIT: I have never been so wrong in my life. The music is now looped. Game changes: 3/17/2016 Woah, 10,000 views. Thanks, guys! :D (Every time new attack patterns are added, the highscore is reset) 11/30/2015 100 love-its benchmark; now this project can't be suggested to be featured, ha ha. 11/14/2015 3.1 (Current version) Fixed a glitch where the "circle" pattern lags out the game, causing players to "teleport out the box"; also, I finally decided to loop the music for good. Shouldn't affect the difficulty of the game, so the highscore isn't reset. 11/09/2015 3.0 Updated game and added a new "circle" pattern (it only appears during RED mode, because it's unavoidable in BLUE mode). 11/10/2015 2.1 Changed a very minor detail to prevent possible spoilers; but if you're here, you most likely know it already anyway. Doesn't affect gameplay, so the version number changes only by a decimal point. 11/09/2015 2.0 Updated game to fix lag issues; added a new "X" pattern. 11/08/2015 1.0 Original version released, prone to lagging (it used lots of clones for the lasers).
