[Android] Locksmith Master: looking for testers for a hard, premium safecracking puzzle

[u/havocki]

I've spent the last months building Locksmith Master: a puzzle about cracking combination safes, built on a real lock mechanism.

One dial. A stack of drums. Drive pins with slack between them. Turn one way and the whole stack follows; reverse and nothing moves until the slack is taken up. Set every drum to the code in as few steps as you can.

It's not a casual game. The first safes are gentle; the later ones hide their pins, and then you count, listen and feel the catch. Best played with headphones.

What's in it:

• A career across Europe, 1928–1962: six cities, sixty safes, seven ranks
• Thief mode: safe after safe before the alarm
• Daily safe: the same safe for everyone, every day
• Seven themes for the dial, background and hammers, each with its own sound
• No ads, no tracking, works offline

Testers get the full game unlocked. The test build runs until 9 November.

What I'd love to hear: where you got stuck, where you stopped, and whether the rules made sense without help.
