A match 4 game based on Lumines with YouTube videos playing in the background!
Use the arrow keys to move the blocks, up key to shift them around, and down key to make them drop.
The game could probably need some more balancing, so any feedback on that will be much appreciated.
There's a few more commands that aren't listed in the game:
Press P to pause the game (and should the video ever stop, try pausing/unpausing to get it started again).
Press R to restart the video in case it gets stuck and pausing and unpausing it doesn't seem to help.
Press N to change song and skin (only works in arcade mode).
You can press space instead of using the down arrow key to make blocks drop, if you prefer.
You can also shift the blocks by pressing Z or X rather than the up arrow key - this way, you can shift them both clockwise and counter-clockwise.
There is also a mouse mode hidden in there - press M to toggle it.
