The incredibly prolific rabidwolf9 has released a demo to his D-Mod entitled Relic Hunter.
While this is only the third D-Mod our lupus pal has contributed to, he has created nearly three dozen developmental files over the past twenty years. That expertise definitely shows in this demo, where deft scene work and clever scripting show a great deal of craftsmanship. For example, in the dungeon you learn of a new feature where you can press 'Q' to see where enemies are located on the screen, very useful for screenlocks where enemies are hiding behind opaque walls.
Even though this is a demo, and will likely never be finished, it's definitely worth taking a peek to see a D-Mod full of quality.
