I voted Yay (it couldn't hurt at least) but I'm not interested in any items. Unless they are super awesome, which they may be...
But even so, I would much much prefer to just donate my money. That way I know you get most-if not all-of my money rather than the relatively small percentage you would receive from Merch alone.
The amount of enjoyment I received from your games, especially as a late-bloomer compared to most around here, I say you should open up your donation system again (perhaps give a small discount to Saira to those who donated?). As soon as I saw your site for the first time you had already closed the donations so I never had the chance.
I'm a college student, so money is tight but I would have no problems donating any reasonable amount.
I would certainly refuse any discount you may or may not offer if you decided to open donations and yes, that is a halo over me head :P
