NOW THIS IS WHAT I CALL "ENDLESS GREED"!
There could not possible be a game that implements this restriction better than this.
Artstyle is nice, simple and effective, 3 colors is all you need, although white color of font doesnt't fit everything else, but that's nitpicking
Gameplay is the definition of "Endless Greed", don't get it twisted.
Music is perfect for this kind of games, really puts you in relaxed state, similar to having a drink, asking to put one more coin in
Only one thing I could ask for - to not display all icons simultaniousely, you've gotta keep up the tension of showing last item
