At the moment, we don't accept pledges through PayPal, but once the campaign is over, we will add PayPal option onto the Kickstarter page as well as our homepage, so please mark your calendar and make sure to come back!
First of all thank you! One cool thing you can do is get other people to back the Kickstarter or vote for us on Greenlight. Although if you want to be extra-extra awesome, post about Basement on your forums, message news sites and ask them to cover the game. You can also tweet, post it on facebook, go nuts, be our viral media! :)
