That one left me quite puzzled. Need to collect my thoughts on that...
Honestly, after playing it once and even reading the help page (which I ignored at first as 90% of players will do) I still don't know how I would really play it. I noticed I have to click away the bad cloudy things, but what's the percentage bar? And how do I make the "good" things entering the mouth if not by accident? No clue!
The background music is also a bit intrusive.
I think the general topic is a nice idea, but needs a better game concept. Or maybe it's just not my taste, sorry... ^^;
