Persistence is Key

Carry the key to the door to unlock it! You can throw the key through spikes, or throw it at enemies to defeat them, but you can't climb ladders with it. There are 3 levels.

Controls:

• Move left/right or climb up/down ladders: WASD keys or D-pad
• Jump: K key or A button
• Pick up key (when standing on it) or throw key (when holding it): J key or B button
• Restart level at any time: ENTER key or START button
• Exit game (Windows only): ESC key or SELECT button
• (Note: I tried to implement some basic gamepad support but didn't have
  time to fully test it. If you're able to try out a gamepad, please let me know whether it works or not!)

Made by me in a week in GameMaker Studio for GBJAM8. I ran out of time to add audio. Oops.
