The End is Nigh is effectively an unofficial sequel to Super Meat Boy: it's a reflex-oriented platformer with quick deaths, quick respawns and very dark humour. Protagonist Ash "flops his way through a future of pain and suffering" in search of a friend whose body parts are spread around a spike-filled hellscape. Collectibles are tumours.
I think The End is Nigh is better than Super Meat Boy, and while that might be controversial for some, I doubt anyone would argue it's not better than Super Meat Boy Forever, an autorunner primarily designed for phones. The cartoon darkness of The End is Nigh is more appealing than Meat Boy's referential, jokey presentation, and I think the level design is more interesting too.
