I honestly cannot put into words what itch this game scratched - I've never played anything quite like it and, like a few other people said, I finished this game in two long bursts because I just couldn't possibly put it down. That time was full of "just one more floor," as "one more floor" turned into finishing the run, then into "just one more run", and the cycle repeats. The action is complex yet rewarding, with each enemy having a particular moveset that you can learn - it feels incredible weaving around and avoiding all damage because you've learned how the Grotesques move and attack, manipulating enemies into killing each other, and using these skills (and a great deal of luck) to finally make it to the bottom for the first time.

Plot is obtuse, progressing based on vaguely defined puzzles, experimentation, and death; you never quite know what's going on, but that mystery adds to the barren, dingy, and dark atmosphere.
