Tonight I finally summoned enough patience to finish all of the advanced test chambers in the original Portal. I only solved two of them back when the game was new, and eventually got distracted by a sea of other games and worlds. Fast forward to today and I finally got both the Fruitcake and Vanilla Crazy Cake Achievements! Huzzah! I did end up having to complete the last test chamber on my Steam Deck. Apparently when Portaling up and down it’s difficult to turn yourself when playing at a higher refresh rate. I suppose I could have forced a lower framerate, but figured I could just whip out my Steam Deck and finish the job.
All that’s left is to beat the challenge maps. I wonder how many decades that’ll take me? 😛
