We Were Here Too My opinion on it is basically the same as the one on
We Were Here.
I thought this paid episode would be a bit longer than the free one, but I didn't notice much difference in content and length. There was still time pressure involved in some puzzles, and it still didn't add that much to the challenge and fun, IMO, although at least this time it didn't impair the threatened player by reducing their field of view. The final puzzle required to solve in order to let both players escape was still pretty shitty, not based on clues and only solvable by accident or by replaying the game from scratch (although it doesn't really have replay value). And the background felt a bit random, it didn't seem like I was experiencing a consistent story that I should pay any attention to. It was not scary either, there were sometimes ghostly voices but they were hard to understand.
On top of that, the game was somewhat unstable. I had a crash on start the first time I ran it, while my co-op partner had endless loading with black screen. A restart of the game on my end and a reboot of my partner's PC on their end solved the issues, but it also happened to us on two different occasions that one of us fell through the floor of the level. And when we had to restart the game once in the middle of our playthrough, two checkpoints and something else we had done before hadn't been saved and we had to repeat two puzzles which was tedious.
All in all we still had fun, it's a neat distraction for two, if you're into escape room puzzles, and since I only paid 3 EUR, it was well worth it, but I think at the regular price I would have been disappointed.
