Sorry if this info is somewhere on the forums but I was not able to locate it. My question is...I pledged $25 originally via the PayPal campaign and now would like to bump it up to the $50 Early Backer Select. If I just pledge another $25 will that bump me up to the next tier? I now have a friend who wants to play with me so I'm looking to snag that extra Alpha/Early Access key. Thanks in advance for the help!
