Still chugging along!
I have added all the code for every Element and Technology used in Age I.
I changed some of the core HaxeFlixel classes to be able to include special icons inside Bitmap Texts so I can show my icons in the text like "Generates 1 [[food icon]] on Death".
I added Tooltips which work even if you mouse over an icon inside of a Bitmap Text object!
...and I've tweaked some balancing. Almost to the point where I can totally play through Age I to see if it works!
Once that's tested, I think I will start looking into the actual aesthetics of the game - probably choose another font and adjust ui a bit to look better (more whitespace, etc).
Still enjoying how this is going!
