I'm pretty split on Ruins. The level didn't leave much of an impression on me the first time around, so I went into Ruins mostly blind. The beginning is a quite dark and makes jumps a bit unpredictable, which unfortunately is a pretty significant problem throughout the level. For me, Ruins wasn't that fun, with a lot of it being incredibly simple, but occasionally having camera triggers that can be quite obnoxious, leading to some moments that feel pretty irritating when you die. I feel like this level would be around a 7 star in difficulty if the gameplay weren't so unclear at times. On the other hand, I think the theming is really well done, and I like a lot of the robotic elements. I especially like at 20% the demon which is from Cheat Codes, the Event Level directly after Ruins, and that shows a bit of continuity in this level I really like. I can't say the gameplay is that bad once you get it down, but it unfortunately really sours the experience despite strong theming and some very cool visual effects. I think the strong elements in this level propel it enough to be pretty solid, but just barely not enough to be a level I overall like.
