This is a relatively short Doom II map I designed and built over the course of a couple of weeks in my spare time, with no prior experience with making Doom maps. Thanks to Youtube tutorials on how to use Doom Builder 2, here it is! The map is split into a few little areas that have their own visual pallete, and hopefully whoever plays this will find it a bit of a fun, but brief challenge (I didn't go out of my way to try and make it very hard though). Give me your thoughts and criticisms once you've played it. I'm keen to improve my level designing skills, since I'm currently studying a Game Design course, and I'll likely be continuing to make maps in my free time!
