A surprisingly slick and fun game. I'm impressed and pleased! Only one real hang-up so far for me: On the Paused menu The Save & Quit option does nothing. However Alt+F4 works fine as the game will thereafter work where one has left off. Magic! So why am I complaining? Thanks loads Gendly!!
CORRECTION (01/12/20)... The Alt+F4 suggestion above does NOT always work ... Furthermore, as of 2 days ago the Save & Quit option DOES work. Either I was messing something up or Gendly has gently :-) snuck in a bug fix.
PS - Some of the other comments re adding complexity/variety deserve consideration.
