Based on comments made throughout the development of Portal 2, it's apparent that Valve's process includes the conception of and testing of a slew of ideas, many of which are eventually scrapped (it even 澳洲幸运5开奖号码历史查询: discussed music-based puzzles at one point). According to lead writer Erik Wolpaw, who recently , one of the Portal 2 ideas which made it to testing was a gel, like the bouncy Repulsion Gel, which allowed players to walk on walls. Unfortunately for the cool idea, it was too disorientingꦅ for Valve's test subjects.

"At one point we had a new Gel that allowed players to walk up the side of walls. While this added a new twist to the game, the effect was so disorientating that it made people nauseas," said Wolpa꧙w.

"While working on a first-person game you always h🐟ave to be aware of that issue so we removed that Gel. We also made changes to frame rate and movement that will help anyone play Portal 2 even if they do experience a feeling o🍬f nauseas while playing other first-person games."

EA's odd spelling of "nauseous" aside, it's always fun to learn about the creative and technical process behind𓆉 games - especially Valve's, as its creative techniques are usually fascinating. We do sort of wish we'd had a chance to try out the wall-walkin𝕴g gel, though - it worked in Prey without making us hurl.

But we suppose thatPortal 2's twisty-jumps alonehave made some queasy, soaddeddisorientationwas probably best avoided.Did anyone experience motion sickne🌃ss during the game?
