Look at these people whining about how they can't collect coins.. Well guess what, you don't HAVE to collect all coin and you are not SUPPOSED to.. I suggest you look at the first item from the last row at the item shop..
You are supposed to collect as much coin as possible, not collect all the bloody coins ..
It's funny how most top comments complain about the lack of numbers and stuff and I must say: it's actually nice to have a game like this.. One that breaks through the other "strict" ones, like most games are right now (in most of which you need a wiki page open to play) ..
If you see a perk that says "increases food generation rate", you can go like "sounds nicer than the others" and just get it .. Feel free in your choices .. Get what you think sounds better..
