Keys and Cowls is a rather difficult retro platformer about using your wits and reflexes to infiltrate the headquarters of a dangerous doomsday cult.
This was originally made for GBJam5. I have reworked or redone almost every part of the game since then. I've more than quadrupled the number of levels, added dozens of secrets, and special content for the players who go to extremes of collection, pacifism, and self-preservation.
I've played this hundreds of times, but I need feedback from other players to make it the best it can be. If you do take the time to play this, please let me know if you run into any bugs, get trapped, or if anything seems unfairly difficult.
