Since this page is missing a lot of context, this game was developed by Phr00t, who specializes in procedural generation (and VR now apparently). The game was released on Desura (RIP) back around 2012, but thankfully is now available for free on the dev's old website for the game: https://gentrieve.wordpress.com/
This game falls into a lot of the same proc-gen pitfalls - room design is a planner's nightmare but also fairly samey once you've gotten past a couple "worlds", and enemies are either spheres or squares with spikes and turrets grafted onto them. Still, the design is never incoherent and worlds are short enough that the game keeps moving, and I think the textures and music help give the world a hostile feeling to it that keeps it from feeling like generic assets thrown around. I've never stuck with it long enough to finish it (assuming that's even possible), but it was nice to check back in after 10 years.
