I really enjoyed this at the start, and it was surprisingly a long time before you got the ability to make two portals. Even with just one, some of the puzzles were really involved. Sadly, I feel like past Chapter 5, it follows similarly with Portal 2. Get sent into an abandoned area and make a new friend; have one terrible room where you do nothing but toss white gel everywhere (this seems even bigger than the one in P2); slowly get a few more complex puzzles up to ch7; introduce a new mechanic (pretty cool); and it only has easy puzzles, feeling like they need to do another sequel just to fully utilize it. Then you get to the final boss, and yeah, it is different than the others, but it is still just as repetitive. At least the dialogue here wasn't bad.

Is Portal Mel Stories worth playing, or are there any other mods? Most seem to have complaints about getting way too complicated too quickly or just annoying humour.

It's wild how this is not readily available on Steam and even GOG. I guess it's easy enough to blame Activision for it. It's only two more hubs, with the first being much smaller and acting like a tutorial. I tried the new class for this one since I figured it would be specifically made for her, but once you get the 4th weapon (pretty early on), the difficulty becomes a huge joke. The hubs themselves are the most straight forward from all 3 other Hexen games, which was a bit strange, and it's a shame there isn't more after how nice the final hub was.

Hexen, but in Quake! but at least there's no respawns this time. Unfortunately, I fell victim to a huge bug with the treasure key. Normally the clue and item can be in three different areas depending on how you progress through a certain point, but I spent an hour going in circles, clearly missing something. I looked it up and realized I inadvertently fucked up one of the paths and was locked from completing the hub, forcing me to restart. The only other hub that gave me some trouble was Egypt, but I can forgive it for how sick it was. 

I really need to find more games like this.

It was so satisfying trying to figure all this out and piece things together. The search engines worked very well, and the optional content really helped to bring the entire tree together. It seems like everything was clearly spelled out or had little hints here and there to not resort to guesswork. I loved how you needed pictures of each family member before being able to complete them. Unlike Obra Dinn, going back to look at old clues and evidence is very easy, as it's all done in the same area rather than walking across an entire ship. Though it loses out in the style of being pretty blank and generic, the experience carried it hard for me. Pretty crazy, this was free and took me a little over 6 hours to reach 100%.

It was a bit weird that they had to let you know on the final stage how to triple jump... I really loved the first character playthrough and expected the unlocked characters to have some differences at each stage, but unfortunately, each character only has a unique final stage. These characters also don't have letters to collect, so every sidepath feels really bad, yet you will still need to go to most of them for the S rank. It was still enjoyable with the slightly different playstyle, but I'm still disappointed there weren't even small variations to each stage while keeping the themes the same.  

I learned after finishing the game that there is going to be a free update with even more characters, reworking some of the original levels, new levels (the city looks nice), and a randomizer mode (I have no idea how this will work out). I am excited to go back to this in the future.
