Thematically, Corruption is quite one-dimensional, focused around a malicious program destroying (presumably) the level. This is conveyed to the player through broken code, copious glitching effects in both the foreground and background, and some memory sections with broken, monochromatic decoration. I like some aspects of this; I think the theme is best translated through the block designs, such as the part at 0:14 where the design interiors are constantly glitching and shifting, and some of them even completely fall away or break apart. This does a good job letting the player know what the overall theme of the level is, while also adding a layer of memory to the level to confuse the player as the structuring layout is quite wacky and unintuitive, which feels like something malware would naturally do.

However, the overall execution of the theme is pretty lacklustre. The theming is quite inconsistent between parts; the aforementioned block design effects are never used again throughout the level in favour of more typical squares/rectangles connected by lines, and while this does still resemble technology, it sticks out noticeably against the aggressive glitching used in the backgrounds of most of the midsection. I also think the inclusion of the text and code segments left a lot of potential out; Killbot (which is a clear inspiration for this level) used code to turn the whole level into something resembling a bossfight as the virus is constantly messing with the level and the player (there's even a whole deletion sequence at the end to finish off the level in a satisfying way). Here, it feels more like an afterthought and really only serves as an occasional visual accent, with the smooth animations on the windows feeling pretty out of place, and the actual code being used infrequently enough to not feel important. The text as well feels too edgy for something themed around malware, with the massive "why won't you stop" and "critical failure" setpieces particularly standing out as feeling quite out of place. In general, I just wish this level went all in with a specific idea like Killbot does, rather than trying to maintain a specific aesthetic and "edgyness" while still using some elements of malware, as it leaves the level lacking on both fronts. I would not recommend this for rate, but it's far from a bad level and I'd be interested to see TacticalFahrrad's current and future works.
