What do you mean? To support you just pledge on Kickstarter, the link above goes to his website which has another link to the campaign page, or you could just search it on KS.
The game you can download (demo only atm) from here or Steam, once you pledge I think there's a link for an updated one, but there's not much else in there yet. A little prologue and cutscene, the main bit is same as the standard demo.
I clicked the buy now under the tier level I wanted to support it but after the payment clicking on the return to merchant didn't work on paypal. Will you be emailing us updates to Alisa and a link to the "The Arrival Demo" to the email attached to our paypal emails as well as the final codes to the game and costume? Since this isn't like supporting on kickstarter where we can see all your updated posts on the campaign page as a backer and access messages there.
You will receive an email with your download for the Arrival Demo shortly after you bought a tier. (I try to check my emails as often as possible and I send these emails by hand)
On release you get your rewards send to the same email address.
In case you bought a tier with physical rewards, an email will be send to you to ask for your shipping details.
