So, The Void... an interesting game to put it lightly.
The only snippet I could think of was "the most surreal Harvest Moon you've ever played". This is mainly because you spend a long time growing colour and exploring areas, talking to the different denizens (since they're not exactly people) of the world, earning their trust through gifts and settling into a routine to constantly feed your demand for colour. Except that it's not like that at all, instead of growing carrots and turnips you're growing colour to manipulate the world itself and instead of an idyllic routine of rural labour you're desperately trying to please half-dead monstrosities from fear of being banished to absolute death for corrupting the nymph like "sisters" they protect.
The mechanics take a leaf from Okami's book, drawing symbols with precious colour to attack enemies, create shields or give colour to trees so you can harvest them later. But unlike every other game where you triumphantly return the grey world into glorious colour you have to tread carefully, colour is insanely precious, the moment it is no longer coursing through your veins you die. Your body constantly converts lympha (colour which affects you attributes) into nerva (colour you can draw with) so it's a constant balancing act between having enough colour to do stuff with (and grow more colour) and having enough colour in stock so you don't run out before you get a new deposit. Oh, and it's also made very clear that colour is potent and dangerous stuff, and you do not know how to use it properly, the more colour you spend in an area the worse off it gets, leading to almost a pyramid scheme like scenario where you constantly need more colour to fuel your progress through the world but as you do the world gets worse and worse unless you use colour wisely and sparingly.
The game is mainly split between the void and the chambers inside it. In the chambers you talk to the sisters and brothers, fight enemies, find hearts and colour and plant trees. In the void time passes and you convert lympha in to nerva. The time passes in cycles of 99 ticks, so in each tick you convert lympha into nerva and each cycle the situation changes (e.g a tree you plant with colour will "fruit" in the next cycle and will give diminishing returns for three cycles then lie dormant for five). This makes everything desperately urgent, not only have to balance the different colours and what forms they are in but also time events so they flow into each other (and story and random events throughout the game always force you to replan). Basically it's desperate, frantic, yet cold and calculated at the same time.
Did I mention it's beautiful? It really looks amazing, each sister's chamber has it's own vibrant and unique feel, the brothers are suitably horrendous and dignified at the same time, everything from the the menus, to the chambers to the void itself screams "art game".
It can, no will, also be very frustrating, at least at first as you are learning how to do things. While a lot of the difficulty and constraints add to the atmosphere (it wasn't called "Tension" in Russia for nothing), there are also some frankly just irritating design choices and sequences in the game. You also might have to back track a fair bit, realizing you stuffed up something a few cycles (about an hour) back and have to load a save from then can be very annoying. and I do admit to cheating a little bit, using the console to get a few extra drops of lympha in some desperate moments, but once you learn how the game works it shouldn't be too hard. There's also a lot of trudging around familiar chambers scavenging any morsels of colour you can, but randomness and the control you get later in the game alleviate that a fair bit.
I don't really want to outline the plot or anything because it's so interesting and also ambiguous but trust me when I say it also does some really interesting things with it's cast of surreal and fabulous characters.
Oh boy, that was too many words. Clearly I like it and it's creative enough for me to want to spout on about it. I encourage you to try it if you are all interested in artistic games and are prepared to endure or even become absorbed in tension, desperation and confusion. Also be warned there is a fair amount of nudity in the game, artistic nudity but nudity nonetheless and some people could find bits of it uncomfortable.
tl;dr Get The Void, it's awesome*
