Update 0.7 out today!

March 27th, 2014

And here we are, with version! This version brings in a whole raft of changes in two main areas: graphics and the weak force.

The Weak Force, while really interesting, has been a bit of a tough nut to crack. The good news is that I think we’ve got it! The big issue was that the mechanics around the Weak Force were inherently unforgiving: it was far too easy to let important particles decay, and far too easy to get stranded without a way to finish a level.

With that in mind, I made 2 basic changes: decays are longer, but triggered by explosions (allowing both time and control); and W bosons now decay into electrons and neutrinos (rather than up and down quarks, which were much more deadly). Neutrinos (which are new!) give you 2 pieces of data, meaning that it’s now possible completely recover the data from a change.

The other big change you’ll notice is a bunch of graphical improvements, especially around examination mode. We’re using some pretty awesome shaders to help highlight the player particle and whatever you’re examining, and are using this same effect for everything from invincibility to the slowdowns that introduce new particles.

Finally, there’s a bunch of small bug fixes, and some new menu features. Controllers should be fully supported now, and all of our options are nicely in the game menus.

That’s pretty much it for this build - as always, please let us know what you think! - Paul



  • Weak force mechanics have changed - W Bosons now decay to electrons and neutrinos
  • Weak force changes - explosions now trigger decays
  • Neutrinos! (they don't have fancy graphics yet)
  • Chapters 6 and 7 updated to deal with this
  • Menu controls (keyboard/controller) work now
  • Activating the Steam Overlay now pauses the game
  • Examination mode, Invincibility and 'Focus' mode use a fancy new shader
  • Mouse-overing objects in examination mode highlights them
  • Resolution options in menu!
  • No more annoying options popup!
  • Off-screen indicators are both prettier and break the game less
  • Small bug fixes

A Day In The Recording Studio

March 25th, 2014

It’s 5pm on a Friday, and the day’s really just beginning.

Our lead voice actor, Bridie Connell, has just arrived to the SeeThrough Studios offices. Our audio engineer, Byrce Halliday, is on his way. In less than an hour, we’ll have begun the mammoth task of recording 110 lines of dialogue and 108 attribution lines with 11 different actors in a weekend.

But before we can start, we have to construct the blanket fort.

We chose to do the recording in our office simply due to availability - there was nowhere else where we could guarantee access over a full weekend for no cost. But the office isn’t perfect: the air conditioner is noisy, so we have to turn it off, the meeting room we use heats up astoundingly easily, and the ceiling reflects sound like a mirror… for sound (probably not the best analogy).

One of our voice actors, Nick Starte.

To combat this, we made a blanket fort - the blankets absorb the noise, you see. On the Friday, it was built out of a whiteboard, a chair, a keyboard stand, a rather unstable hat stand and three blankets. On Saturday, we traded out the hat stand for a much more stable clothes rack.

What resulted was a pretty awesome little studio, except for the niggling problem of overheating. Bryce brought an awesome collection of dials and buttons that I got to press and turn on the Sunday, and all the actors brought their A game.

Mixmaster Bryce is working his magic.

I think what astounded me most was how smoothly it all went. We got all 218 lines done in the one weekend, and had time to workshop everything we wanted. We made up 2 names of characters on the spot, and fixed a bunch of lines as we went. Some of the lines were hilarious to hear (hearing Carlo say ‘Hast seen the white whale?’ about 10 times in a row in a variety of ways has got to be my favourite recording of the weekend, followed closely by Bryce’s attempt at a German author of a Physics textbook), and some were unbearably sad. In the end, we’re pretty confident that we got everything right at least once.

So with one major hurdle down, we march closer to the finish line. Now for the rest... - Paul

“I haven't cried playing a video game before; it's not like it's a habit. But there's something about the loneliness of being a down quark all alone in a subatomic space that really underlined the joy in finding an anti-down quark to combine with.”
The Guardian

“The game feels fantastic. It’s a joy to whiz around the simple environment. This game illustrates the idea that a game doesn’t have to be visually packed to look good; indeed, its artistic style is reminiscent of flOw.”
Kotaku AU

“It’s a story-led, arcade puzzle game that seems to have a lot of intelligent thought about it.”
Rock, Paper, Shotgun

About the Game

Particulars is a game with a unique combination of arcade-action and puzzle gameplay, set in the mysterious world of subatomic particles.

Taking control of a single quark, you must negotiate the fundamental forces of the universe. Other particles will push and pull at you - you'll always be on the brink of losing control and being dragged towards annihilation!

Woven through the game is the story of Alison, a young physicist with a troubled past. Her journey through the subatomic world is drenched in memories (both good and bad), and will ultimately lead her to some surprising revelations.

It is awesome. Being the main target bashing protons and electrons together to create collisions and explosions, getting data, the amount of obstacles thrown at you. It's one of the best puzzle games I've ever played.

This is game simplistic and enjoyable. There are a few things that i don't know if are suppose to be that way or not, but all the problems are not in the game play and in more of hte cutscenes and vanity stuff like voice overs. The game play is easy to learn and it enjoy able. But what i find impressive is that the gameolay isn't connected to a plot but there are quotations and brief cutscenes that are impactful and paint a pretty clear picture of the main characters life, it may be simple quotations and cutscenes but they are impactful enough to make me sad and almost in tears. it is trully a game to play and it will make you feel.

This game is pretty interesting but in a good way. Storyline behind the game is a bit interesting even though there's still a few holes in the story (because its still be worked on) and some of the voice dialog doesn't match up with some of the written dialog in game, though that's subject to change in the future. For the most part though game play is quite simple and it can be used with both keyboard/mouse or a gamepad (xbox controller). By looking it as far videos goes it very hard to understand and may even seem uninteresting but once you get hands on the game, you begin to understand what's going on and how it's supposed to be played. Overall it's worth trying out and only tiny gripe is that the dialog and voice dialog don't match up but like i said earlier that's something that's bound to change later on in the develop.

Particulars is not a game for everyone, and that's a good thing. Often we see game developers try to please the masses and in doing so please no one. The team at SeeThrough Studios have chosen to create a game they wanted to create and this becomes clearly evident as you experience Particulars.

Particulars explores unexplored territory with very strong writing in an arcade-action puzzle game, never have I played a puzzle game of this difficulty and actually been drawn into the story. You experience feelings of futility as you realise the actions you're performing in the game are on such a microscopic scale that in the grand scheme of things they have no effect. The interactive nature of the game enhances this and helps you realise how our main character feels and you're able to see correlations between the subatomic world and the world which our main character lives in.

While it may seem simple at first, as you delve deeper into the story you start to see connections between the story and gameplay, and as the story intensifies so does the difficulty of the puzzle. As the game progresses the need for good puzzle solving and solid execution of the puzzles is needed, this is because of the games arcade-action nature where everything happens so fast and all your actions have a passive effect on everything around you.

If you're not afraid to use your brain for a couple of hours Particulars is the game for you, with its strong storytelling and it's surprisingly difficult puzzles this game is easily worth the price of admission.

During it's current sale I can 100% recommend this, put down that burger and play this instead!
