Thanks for playing! I'm glad you enjoyed my little game. Lockpicking it's sort of a "sound" puzzle. You must find the sweet spot (there is a sound cue). It was intended to feel like you are actually lockpicking, so I hid the "puzzle" and made it entirely by sound. I might change it to make it more clear though. The ending of the stage is something that I'm still figuring out. I'll be updating the game with more stuff if you are interested in giving another try. Thanks for the feedback, it's really appreciated!
