Blood Dungeon is the future games deserve
Blood Dungeon is the kind of game that makes me want to simply repeat "BLOOD DUNGEON! BLOOD DUNGEON! BLOOD DUNGEON!" for 300 words and call this post done. It's the kind of game that felt like the future of the art circa 2010: a work with, regardless of team size, a clear authorial voice; with simple pixel art which seems to fizz; with ultraviolence and verve and arcade flair; with a sense of humour and an economy of design.
None of these things are a surprise. Blood Dungeon is the work of (among others) Mark Essen, the creator of Nidhogg, which I first played in 2010. His work felt like the future of the art then and it still does now.
For all Blood Dungeon feels like the product of a simpler era of freeware game design, it's also tied to indie gaming's most modern expression: the autoshooter. Like Vampire Survivors, your challenge here is to avoid enemies and kite them around while your weapons carry out their task automatically. This is married to a platformer in which you stick to every surface, letting you clamber up walls, hang from ceilings, and balance along tightropes with ease.
