cognitohazard card profile
cognitohazard is currently placed at Rank #35 in the All Rated Extreme Demons List (AREDL). The list records the level's publisher as MercuryDT, and this card carries the Uncommon rarity in ExtremeGacha. That rarity has a published 30% chance in the shared daily-draw table, so its collection value reflects the current rank range rather than a hidden score.
The hardest and most skillset varied extreme demon that was made for MatMart GDCIV2, featuring 2 player parts, very spammy gameplay, a very original memory ship and random elements, it was designed specifically to not be beaten by anyone. It's atmosphere is based on a glitchy theme and an actual cognitohazard in which mind control elements are in place. Along with surprisingly being legendary, and the hardest level of this rating, it's also the hardest level in the 2 player list, the hardest level with 0 frame perfects and the level with the most time spent in pending in the demonlist. Its listed tags are 2.2, Long, 2P, Memory, High CPS, Gimmicky, Duals, Overall, which give collectors a concise view of its gameplay profile. This site uses a locally generated text card instead of a video thumbnail, level screenshot, or other official asset.
AREDL placements can change as the community receives new evidence and comparisons. ExtremeGacha therefore treats Rank #35 as a dated snapshot, not a permanent difficulty claim.
