Hi glitterflounc!
So happy you joined us for the Haunted Rainbow Jam and congrats! You should be able to reply to the email you received from me via the Rainbow Jam and itch.io that discusses the winners. Just include your Steam username in the response to receive your prizes!
I hope that you'll join us for the Fall Rainbow Jam that starts this Sunday! Also feel free to follow me on Twitter, @JustThinkingKay, as I regularly post about Rainbow Jam there.
