Hey thank you for playing! We are happy you liked the "digging" mechanic! There is still much untapped potential in this feature that we may want to explore in a future take on this game (maybe as a full game release sequel ).
We are currently updating our internal build of the game to incorporate sound, music and ui enhancements including an improved ui font that should fix your (and others) scaling issue (see image below). We will release the update after the jam is over and announce it on the usual social-media channels.
