Getting Into the (Rat) Zone

So, via some happenstance you, like many before you, wish to play Rat Sending Simulator. Well. Luckily for you, I am a humble king. And thus I shall outline the basic steps to becoming like myself. a rat king.

Step 1. Rat
You can't become rat kingly without rats, so accumulate them. this can be done by clicking the red "Rat Acquisitions" deck in the rat zone (where you are very likely to be)

You can also be sent rats, and send rats, sending rats may seem counterproductive, but the rat points you gain can be used to buy more rats than you sent, making you a rat profit.
