Finally I got to play your game! :D I had fun with Disc Doom, the graphics are old school but have their own flavor, specially the weapon and the grotesque enemies! I don't know if that was intentional,  but I also liked that you ended up combining Disc Room with another of Terri Vellman's games, Heavy Bullets. ;)

The things that gave me some trouble were probably due to a lack of time, like some strange collisions with the walls and dying right after falling to the next level. But it was a great entry, Erick!
