Lunacid is lo-fi first-person dungeon skulking done right

I lost my way with Lunacid last year, early on after stumbling through a small warren of spongey enemies. Trying it again this week rewarded my patience and taught me that I'd had the tool I needed all along, but dismissed them because it didn't work immediately. Playing beyond that has elevated it from "not my thing but I should cover it because it's someone else's" to "wait, this might be my thing? Damn it".
