The tier with DC is a limited one-off. We have agreements with distributors etc about sales and pricing for DC. We need to adhere to those contracts. We were "allowed" this one tier on Kickstarter if it were limited.
It is true that we are independent and that both games are ours, but that doesn't mean we don't have investors and agreements. KS money goes into development of DOS, not of DC.
(I'm not the best guy to explain this, but this is the gist.)
At the moment, PayPal are tiers only, no add-ons. We need to talk internally about add-ons via other methods, esp the way we're gonna organize that
