Pure Logic now bundled with newly released Mirrors of Epiphany

Greetings puzzle gamers! 27 months have passed since Pure Logic was released. Time flies indeed! A few days ago I released my second game, Mirrors of Epiphany. It's based on a very simple premise: Two-sided mirrors are used to direct coloured light beams from their sources to tar

The Intended Verification Update

Hi,

Here comes an important update that gives you more control of how and when the puzzle verification sequence is being triggered.

Up until now, each puzzle verification has been initiated by a left or right click basically anywhere on the screen (after all signals have been actively set). The exception to this is when a user-set signal has been clicked. That clicked signal has then been changed or reset, basically making it possible to review and change signals for as long as needed before deliberately clicking "anywhere" to confirm.

The upside with such a solution is that it is very flexible, and it requires a minimal amount of time and effort to move the cursor over to some kind of dedicated submit button. The downside, as being reported by a couple of players (and probably experienced by several others), is that if a permanent/fixed signal has been clicked (in good faith that is was a signal that could be changed) the puzzle verification would be unintentionally triggered, with the rage and horror that probably has followed in some of these instances...

So, to make these critical moments much more safe and predictable, and to provide a rather large "confirm button" as close to the active puzzle area as possible, the verification process will now be triggered by clicking the "Click here to confirm..." text itself. The relevant tutorial texts have been adjusted somewhat, and these texts will now turn white when being mouse hovered, to make it as obvious as possible that the tutorial text itself needs to be clicked to advance.

I hope that this is an important step in the right direction, at least for some of you. And at the same time I hope the adjustment doesn't create confusion or any kind of annoying extra effort for existing players, which may be using solving strategies where this accidental confirmation thing hasn't been an issue.

I'm happy to receive any kind of feedback or comments on the update.

Now, back to creating more puzzles for Mirrors of Epiphany :)

The Instant Confirmation Update

Some players love animations, while others would like a more snappy experience, and being able to advance and proceed as quickly as possible.

In addition to a few graphical tweaks here and there, the puzzle verification animation (i.e. the stamping of gates being correct or wrong) can now be skipped by a simple mouse click while the animation is doing its thing.

In detail, the following changes have been made in this update:

If the left or right mouse button is clicked (anywhere on the screen) after a puzzle verification process is initiated, the remaining gates will be stamped correct or wrong at a very high, constant speed.
The training-grounds-advance-next-gate-mechanism is redesigned (simplified into two gradient shadows).
When the mouse pointer is hovered above a signal which is already set to white or black by the player (i.e. not applicable for signals with an initial predefined state/colour), white signals are shown a little darker, and black signals are shown a little lighter, to indicate that this particular signal can be changed. The degree of this darkening/lightening is now reduced a bit, to create a somewhat stronger visual effect when an unset signal (which implicitly is already being mouse hovered) is set to active white or black. This is however a delicate balance. I tried to maintain enough darkening/lightening to still clearly distinguish between changeable and fixed/predefined signals (in addition to providing a visual effect when the mouse pointer is moved across the signal/gate array). But of course, these effects may appear different based on monitor differences/adjustments and player preferences.

Any kind of feedback to the stuff mention above, either as comments to this post, or included in reviews, are highly appreciated. As a solo developer, without a large team to ask for feedback on design decisions, it is super-valuable to get some kind of confirmation if things are moving in the right direction :)

Enjoy the update, and enjoy the Steam Autumn Sale!

PS: If you think you may enjoy playing around with some light sources and mirrors for a few minutes, there's a free demo available for my second, upcoming game; Mirrors of Epiphany. The demo includes the first 10 puzzles.
