it's cute, but...
do NOT forget the phrase you set as your password.
and since it's audible, be conscious of where you are when u put in your password.
but it's fun, and you can play it for a while (the piano) before you log in.
so, basically, cute, annoying, unnecessary...but cute.
Since I have my passcode set to only be asked for every hour I think this won't be so annoying to input. It's working great for me so far, no issues with SubtleLock or LockInfo.
My friend got stuck in a boot loop so I had to to boot + volume up so I can uninstall it for him. Something must be conflicting but I didn't have time to disable all mobile substrate add ons to see which tweak it was.
You can only use the white keys and it might take a bit of messing around with to figure out how it works but it definitely works and works well for me. I'm just looking for something that'll sound good right now. Might test out Walk of Life later
