Thanks so much Eris for the feedback!
It is pretty hard...probably want to play about with the numbers/regen a bit more to see if we can find a nicer ramp up!
Appreciate all the lovely words. There should be background music...perhaps it was switched off on the main menu? I'm curious as to why it didn't play as I just checked myself :< I do know the music doesn't loop though, which we'll sort after voting :) Thanks again!
