Marbland

Enjoyable, I liked the aesthetics and the fights 
My only complaint is that the final fight disrupts the flow of the world by being too difficult

Plut is a Russian speedrunner who has released a handful of maps, mostly small ones like these. In Marbland, one learns that basically every room is bugged with some sort of point-blank trap, most containing just a few monsters. Both maps are relentless with these traps, far past skillsaw or the Casalis or whoever you consider trappy, to the point that I even started laughing. If you are focused on survival, the meta shifts towards preemptively deciding where to run upon hearing the fizzle of a teleport flash or the clunk of a lowering floor, rather than engaging the encounters on their own terms.  

But despite the crude staging, I thought the encounters themselves were consistently enjoyable and well made, like Crumpets stripped down, or cramped takes on Skepland skirmishes. (Now the name makes another layer of sense.) If you blur together the fights into an average pictorial representation -- like those "face of the average human" composites -- you'd probably get a 4.5-monster encounter with an imp and a hitscanner and a revvie and a hell knight, the latter with a suspiciously pink torso. Oh, that still leaves the 0.5 to account for, so toss in maybe half an archvile (the lower half of course) or caco horns mixed with pain elemental arms. Mancubi and arachnotrons are conspicuously absent, being too thicc to navigate these claustrophobic rooms. 

The aesthetics aren't bad. As the stamp-sized versions of the screenshots might hint, the attractive texture choices and pleasant combinations of natural colors go a long way. The looks don't hold up quite as well to closer inspection, though. Although there are nice-looking areas, the mix of assets in a scene can be sloppy, and distinct textures and flats aren't always separated in tidy ways.
