Cute little find the object game.

The game consists of a single large image where you need to find objects in sets of three (i.e. at any point in time you'll need to find all instances for three kinds of objects, no matter in which order).
Each time you clear a kind of object (e.g. all birds, all brooms, all apples), you pick another from a selection of three. There's some strategy to what you pick, at least with the timed challenges (see below).

The amount of objects to be found for a kind is arbitrary to the kind itself (e.g. there will be X birds on the image, Y pot plants, Z candles etc) and is always the same.
The objects themselves differ from each other in their look: a dog may be lying on the ground, another hiding behind a can; an apple may stand on a window, another on the street and eaten to its core.

The image is black and white and when you click an object this gets colored, which is obviously needed gameplay-wise but also helpful from a visual point of view.
When you clear a section of the image, i.e. you find all kinds of objects for that section that you could be presented with in your picks, the section gets further colored, also in its background and unselectable details. This helps you with discarding it from futhers searches.

You need to find objects until you reach the goal of 100 instances total, after which the level ends and you win.
The competitive part of the game is that you're challenged to end it in ever shorter amounts of times (down to 5 minutes).
This makes a hidden-object game effectively morph into a mnemonic one, where you need to remember where the objects you already know are.
You'll gradually grow more and more familiar with the objects and will remember their position and look, until eventually you'll accomplish the five-minutes challenge (which you will probably get close to a few times, before doing).

Sure, all of this is much cheatable and in many ways, but there's no satisfaction in that.
The game provides you with some help in the form of delayed hints (which randomly point you to a tiny area where an object is, e.g. "in this area there's an apple"). Luckily they don't feel too easy and are a nice aid when you don't remember objects' positions.

The background music is ok and suited to the scene.

All in all, the game is a fine specimen of a hidden-object game and given how cheap it is it can be a nice addition to one's collection. Challenges are tied to Steam achievements, which for me was a reason to buy the game in the first place.
