*2024-02-01, version 1.3*

I am spending a lot of time playing this. Just wish there was more puzzles, or a way to reset the game board without reinstalling and losing the tokens.
The other thing that could be worked on is the audio, I like to listen to my podcasts while I play, but even with the SFX and music turned down, the app turns the volume of my podcasts down.

### 5/5 — Genial
