Wow, that sounds so exciting! You guys got it in for Spooktober though and that in itself is a huge accomplishment! The fact that you're interested in extending the game is great considering you all all the time you want without crazy deadlines now~
Seriously, that summoning sequence is a gem and inspires me so much since I love supernatural elements in my games!
Also I knew I wanted to summon the headless pumkinhead from the very moment I saw her (;
I am trying to review all the Spooktober games btw, and can link it on twitter if you don't mind? (:
