What's Enter the Gungeon? I've heard of the first two games, but that one is lost on me.

Same kind of twin-stick shooter rougelike as BOI & Nuclear Throne and it's gotten really popular. Published by Devolver Digital (The guys who also published Hotline Miami) but ALOT more bullet hell-ish. Almost everything is a gun or bullet related pun too, like versing the "Gundead". Lots of shutouts to other franchises, like the Windup gun from Futurama.
