Portal: Reloaded! Full game in just over four hours! Dark Lord Elliott!

Well, not counting the intro sequence, that is.

Portal: Reloaded is the time-traveling, unofficial, successor to Portal 2. Released ten years later to the day, Portal: Reloaded promises to bend your mind in a new way: with time travel!

Also, for anyone that doesn't know, and actually cares, time is not the fourth dimension. There are a theoretically infinite number of spacial dimensions; but time rules over space, and is not indicitive of what space does; only that it exists in the first place.

Now, I'm kind of stupid when it comes to these "slow, methodical" kinds of levels. I prefer the "fast, get it done" type. Time travel, while a really neat innovation, is kind of the hardest form of level for me in Portal. It doesn't help that this is practically a mod based off the Portal Stories: Mel mod; even featuring some of the same creators. These mods really prioritize you trying everything on everything, with everything, and through everything. That's why this took me over four hours to beat. Well, that, and the fact that it's Portal 2, which I have a much harder time with, just in general.

That said though, if you want to give the mod a try, it's available on Steam. All you need is a copy of Portal 2, and you'll be good to go!
