Matchkey

INSTRUCTIONS

Use WASD or the Arrow Keys to move and push blocks. Line up three keys of the same color to open the lock of that color. Keep pushing and matching to open a path to the portal.

On later levels, you can line up 3 blocks that show the four-directional arrow symbol. This will make all arrow locks move in the direction they are pointing. 

If you get stuck, press Z to undo your last move, or press R to restart.
