Freaking amazing work, dude! For your first horror game, this was very lovecraftian and was quite fun to play! The mechanics were straightforward and the writing of the text very reminiscent of ye olde english.
I would like to see this fully fleshed out into a demon summoning simulator! Imagine if you could encounter different types of beasts from cthulu to the king in yellow etc. etc. Lots of potential here! Nice work!
