Release notes (v1.0.15):

Improved the opening door mechanism by adding on-screen progression indicators, making reset clearer, and ensuring the receptor is always 100% synchronized with the blocks' state.
Changed the default keys for the logbook and interactive view to use more commonly used keys in the gaming industry (only applied to new players).
Increased the range of the analyze feature because some players were missing elements to analyze due to being too far away from them.
Hub platform: reviewed the design of the validation button on the console because it was somtime mistaken for a reset button.
Platform 09: fixed a case where an achievement could be manually resolved, but the achievement description indicated that only an automatic solution was acceptable.
Platform 05: adjusted the difficulty level of the sliding puzzle.
Platform 10: reduced the time it takes for automatic notifications to appear, in order to prevent overlapping notifications when a player requests an analysis within the first few seconds of landing on the platform.
Platform 13: fixed a grammatical error in an analysis description (English & Portuguese).
Platform 17: fixed a grammatical error in an analysis description (English only).
Platforms 20 & 22: added more story elements to the levels to make the puzzles more intuitive.
Platform 32: rearranged the objects in the level to prevent a solution that does not work and is difficult to understand.
Engine optimization: reduced draw calls for all UI by using instancing on GPU.
Engine optimization: improved the 3D objects instancing to better reuse past rendered objects.
Engine optimization: improved 3D objects animations in case a vertex is effected by only one bone.
Fixed crash when player tries to close the logbook while zooming on an image in the logbook.

Reflections caused by backlit/technical lights that are not intended to be visible have been removed (bonus: performances in game increased slightly).
A new sound has been added to alert players of execution interruption when attempting to build a block.
Resolved an issue where execution failed to initiate on the first attempt in rare cases.
Visual design of the dotted lasers has been improved to make it clearer to players that they are not actual lasers, but rather visual aids to understand where the lasers will appear.
Level 9 has been reviewed and adjusted slightly to prevent puzzle solutions that may be easier than originally intended.
The size of the symbol on the receptor panel has been increased to make them more noticeable to players.
In level 8, a laser block that was overlapping with a baseboard has been repositioned.
Level 10 has been simplified by blocking unnecessary parts on the cart.
The descriptions of two achievements were reviewed to prevent misinterpretation.
An image at the end of the game has been updated to correct an erroneous illustration.
