Delusion

TLDR Essentially a Lights Out game with a focus on a "spiritual" aesthetics, refined but not very interesting.
Context Delusion is essentially a light-out game with a few extra mechanics. It's clear that the dev went into a lot of trouble in providing a unique experience, but in the end the gameplay and level design is not particularly interesting or creative.
Writing The (minimal) plot revolves around saving a people that destroyed their world and became powerless, but essentially amounts to a few sentences between chapters. Personally, I found it a bit cliché and shallow, and added nothing to the game. Although to be fair, it fits with the overall aesthetics of the game.
Aesthetics While the puzzles themselves are abstract, each level is accompanied by artwork depicting the level's title. The art style is interesting enough, and it's clear that the dev was very invested in it (there's an achievement for literally browsing the album for 15mins; when you finish a chapter, you get a slideshow of all the art of that chapter). The ambient soundtrack is ok, at least it's not intrusive. There is no voice acting.
Gameplay This is essentially a Lights Out game: clicking a cell flips its state and that of the surrounding cells, and you have to turn every cell off. There's a few different tile types (like rotating lit cells, or bombs clearing lit cells). To be honest, the mechanics in general are not very interesting. And it didn't help that levels weren't particularly well designed. Good level design requires the player to find a key step that unfolds the solution, rather that trial-error. This kind of flipping games usually rely too much on the latter, with levels that are too big and open for proper deductive reasoning. To be fair, this did improve in the last 2 chapters where levels seemed more tightly designed, and this was what nudged me into a positive review.
Some levels can be challenging, but mostly due to their open nature as said above. And the difficulty is inconsistent, with tough levels in first chapters and trivial ones in the later ones. Each level also has a bonus collectible (a star) that restricts the opening play and can considerably make a level harder.
Another turn-off is the lack of quality of life features and clumsy interface (has the dev ever try to play the game from start to finish?). The undo feature is a source of frustration: you can only undo the last step, you cannot use it twice in a row, and you cannot undo the last step before failing a level since it goes back to the menu. The star system was also a mess: if you fail a few times the star is no longer available and only gets back after passing the level (meaning if you have to solve it again for the star); and there isn't any clear indication of which levels the star was collected (I just discovered later by pure chance that the level name turns golden when the mouse hovers!). The interface is cumbersome, to restart a level you have to go to the menu, to retry a level for the star you have to go to the level selector. Progress is auto-saved but the individual level state is not saved.
Value It took me 12h to get the stars in the 100 levels. You can always revisit previous levels, and there is a single progress slot. Levels open up linearly. Achievements are related to solving levels, getting stars and counting certain kinds of interactions that you'll get trivially as you progress the game. There are also a couple of achievements that require levels to be solved with a particular strategy, introducing an additional challenge. And there's the “look at the artwork” achievement. There's not feature to download/design additional levels.

The story with regards to the game itself is a bit hard to understand, yet as much as it is, the overall aesthetic and feel of everything holds up pretty well in terms of immersing not the player but the mind into something peacefully alluring. The premise might be simple enough, light the designated number of blocks and proceed, but in practice, it uses more brain juice than I originally anticipated, it's a great game when you want to experience something rather different for a while, far from the blazingly loud and chaotic mainstream games of today. Most aspects of it are well made which complements the many symbolic art pieces found in the game. Would recommend overall for the select few players looking for a well made and functional game in steam's sea of shovelware cash grab games.

This game is very pretty for what is basically a "flip the tile and all it's neighbors" game. There's probably more to it later on, but the core mechanic is to flip the color of the tiles so they all match the target color. Because flipping a tile also flips the 4 tiles that touch it, you'll have to be pretty careful to not exceed your move limit (which I quickly found a bit punishing).
I appreciate the polish that went into the game, but find the core gameplay itself kind of dull, and no amount of polish can fix that. BUT, it's definitely not a resource flip and it's clear that a lot of care went into it. So I am recommending it, but only if you like pure logic puzzles of the type I just described. Personally I enjoy a little more variety, in a somewhat less abstract setting.

Very well-made puzzle game with 100 levels and various mechanics. Great visuals and soothing music. Difficulty more on the casual side but the late levels can be quite challenging.
