Well, first of all, the premise is just... bad. You stare at a blank wall and try to spot imperfections. That's basically the whole game.

I rarely rate 1 star (unless for some AI slop) but here I feel this is justified:

-The most important thing: MY EYES!!!! OMG!! Every time the game changes from night to day, it genuinely hurts my eyes. The transition isn't gradual at all, it's an abrupt flash from almost complete darkness to almost full brightness. Making a game constantly switch between near-black and near-white was a terrible idea. It's genuinely unpleasant to play. -The gameplay itself is extremely simple and doesn't offer anything particularly interesting. -The dialogue appearing on the wall is very annoying, especially against the fully dark background. And there's no way to skip it. -Evening time is the worst part visually. I can barely find anything unless I randomly move the mouse around and accidentally hit a spot. At least full daylight and full night have some contrast, but during the evening everything just blends into the same gray tone. -The RNG also seems to be an issue. Sometimes several seconds go by without any spots appearing at all. It's not that I can't find them, there are literally none on screen. It's especially noticeable at night, where the spots are otherwise very obvious. -The upgrades menu is a bit buggy, mainly the last upgrades that require Insight. They're not marked as purchased, which is confusing. And if they're supposed to be purchasable multiple times, the game doesn't communicate that clearly. It would help to show how many times each upgrade has been bought. -When I bought Temporal Awareness, the game completely broke. New spots stopped appearing, and one spot froze in place so I could click it over and over to farm points infinitely and even the sound got bugged repeating the spot audio over and over. If that's actually what Temporal Awareness is supposed to do, then it still doesn't make much sense. Either way, I farmed that spot and used it to unlock the rest of the upgrades easily. -The flashlight feels completely useless. I honestly can't tell whether it has any effect at all. I don't notice spots any faster with it, and the frame/crosshair contrast actually makes spots harder to see.

So overall, no, unfortunately I wouldn't recommend it to anyone, mainly because of the harsh brightness changes, the bugs, and the overly simplistic gameplay.
