Players can now shoot a portal directly at their feet and then another at a different location, which will teleport them directly to that spot. Previously, nothing happened unless one re-entered the portal to trigger teleportation.
Adjustments have been made to the conditions when two portals are on the ground, allowing for more flexibility than before.
The character's capsule size has been redesigned to be thinner and shorter, enhancing the ability to perform certain jumps. In Room 1, there was an issue with trapping the cube in the second dimension; this has been resolved by adding an extra wall that allows for portal placement at ground level.
Additionally, the HUD now displays in the bottom left corner the key to highlight important elements within the level.
