I had commented on this game about a year ago asking if I could use Hellwomb as an example in a tutorial guide I was making for the Raycasting Game Maker. The tutorial never became a video series as intended, but it is now a downloadable PDF guide with some video examples included. Hellwomb is one of the 12 indie games that is featured.
Thank you again.
