Matchkey

Game Description
You are locked in a dungeon. To escape, you must line up three keys of the same color to open the matching lock. Continue to push blocks and match keys until you reach the portal. Later in the game, you can line up special blocks that contain a four-way arrow. This will force all arrow locks to move in the direction they are pointing.
How to Play
On desktop devices, use WASD or the Arrow Keys to move your character and push blocks. If you get stuck, press Z to undo your last move or R to restart the level. On touch devices, use the onscreen buttons.
